Although reactions of samarium(III) chloride, SmCl3 · 6H2O, with potassium hydrotris(1-pyrazolyl)borate K[BH(pz)3] (pz = 1-pyrazolyl) in a molar ratio of (1/1) in THF afford [SmCl{BH(pz)3}2(Hpz)], similar reactions with K[B(pz)4] gave rise to separation of anhydrous H[B(pz)4]. The homoleptic eight-coordinate complex [Sm{B(pz)4}3] obtained from SmCl3 · 6H2O and threefold moles of K[B(pz)4] was allowed to react with twofold moles of K[BH(pz)3] to give a mixture of three major species [Sm{B(pz)4}n{BH(pz)3}(3 − n)] (n = 2, 1, 0), whereas similar reactions of [Sm{BH(pz)3}3] with K[B(pz)4] did not proceed at all. The acetylacetonato (acac) complex [Sm{B(pz)4}2(acac)], derived from the triflate “Sm{B(pz)4}2(OTf)”, was treated with twofold moles of K[BH(pz)3] and showed its quantitative conversion to [Sm{BH(pz)3}2(acac)]. However, analogous reaction of [Sm{BH(pz)3}2(acac)] with K[B(pz)4] did not proceed. Accordingly, samarium(III) ion was determined to prefer coordination of BH(pz)3 ligand to that of B(pz)4, indicating less σ-donating electronic character of the latter. The complexes [Sm{B(pz)4}2(L-L)] (L-L = β-ketoenolato) in toluene-d8 exhibited 1H NMR spectroscopic equivalence of all four pyrazolyl groups at high temperatures, and are regarded as a new class of B(pz)4 complexes, showing fast intramolecular exchange of their coordinated and uncoordinated pyrazolyl groups. Four compounds were crystallographically characterized. 相似文献

A heterobimetallic single molecular precursor, [Fe2Ti4(μ-O)6(TFA)8(THF)6] (1) [TFA = trifluoroacetate, THF = tetrahydrofuran], was synthesized by the simple reaction of [Fe3O(OAc)6(H2O)3]NO3·4H2O [OAc = acetato] with tetrakis(2-ethoxyethanalato)titanium(IV) in the presence of trifluoroacetic acid in THF. The synthesized precursor was analyzed by melting point, CHN analysis, FTIR, single crystal X-ray diffraction and thermogravimetric analysis. Complex (1) crystallizes in the orthorhombic space group Pca21 with cell dimensions a = 19.2114(14), b = 20.4804(15) and c = 17.2504(12) Å, and the complex undergoes thermal decomposition at 490 °C to give a residual mass corresponding to an Fe2TiO5-TiO2 composite mixture. The synthesized precursor was utilized for deposition of Fe2TiO5-TiO2 composite thin films by aerosol-assisted chemical vapor deposition (AACVD) on glass substrates at 500 °C using argon as the carrier gas. Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray powder diffraction (XRD) analyses of the thin films suggest the formation of good quality crystalline thin films of an Fe2TiO5-TiO2 composite with an average grain size of 0.105-0.120 μm. 相似文献

Pure nanocrystallite magnesium titanate (MgTiO3) was conveniently synthesized by thermal decomposition of a cheap and water-soluble heterobimetallic single source precursor [Mg(H2O)5]2[Ti2(O2)2O(NC6H6O6)2]·7H2O at low temperature. This single source precursor was obtained in high yield and in a crystalline form from the quaternary system of MgO-Ti(OC4H9)4-H2O2-H3nta (H3nta = nitrilotriacetic acid) at pH 4.0. It was characterized by elemental analysis, IR spectrum, NMR, thermal gravimetric analysis and X-ray single-crystal diffraction. The morphology, microstructure, and crystallinity of the resulting MgTiO3 materials have been characterized by transmission electron microscopy and X-ray diffraction. The TEM image of the resulting MgTiO3 powders only consists of the nano-scale crystallites with the crystalline size of 30-100 nm. 相似文献

The scope of formation and structures of tungsten-iron-sulfur clusters has been explored using reactions based on [(Tp*)WS3]1− (1) as the ultimate precursor. The reaction system 1/FeCl2/NaSEt/S affords the cubane cluster [(Tp*)WFe3S4Cl3]1− (2), which with NaSEt is converted to [(Tp*)WFe3S4(SEt)3]1− (3).Clusters 2 and 3 contain the cubane [WFe3(μ3-S)4]3+ core.Complex 1 with FeCl2/NaSEt forms [(Tp*)WFe2S3Cl2(SEt)]1− (4) with the cuboidal [WFe2(μ2-S)2(μ3-S)(μ2-SR)]2+ core.Treatment of 2 with excess Et3P yields the edge-bridged double [(Tp*)2W2Fe6S8(PEt3)4] (5) with the [W2Fe6(μ3-S)6(μ4-S)2] core. Reaction of 2 with excess leads a mixture of products, from which [(Tp*)2W2Fe5S9Na(SH)(MeCN)]3−(6) was identified.This cluster, as closely related [(Tp)2Mo2Fe6S9(SH)2]3−, exhibits a core topology [W2Fe5Na(μ2-S)2(μ3-S)6(μ6-S)] very similar to the PN cluster of nitrogenase. All reactions were carried out in acetonitrile. The structures of 2-6 were established crystallographically as Et4N+ salts. In the cubane series, substitution of tungsten for molybdenum decreases the [MFe3S4]3+/2+ redox potential by ca. 0.20 V but has a negligible effect on electron distribution. This work expands the small set of previously known weak-field W-Fe-S clusters, demonstrates the existence of tungsten-containing edge-bridged double cubanes and clusters with the PN core topology, and introduces a new cuboidal core structure as found in 4 (Tp = hydrotris(pyrazolyl)borate, Tp* = hydrotris(3,5-dimethylpyrazolyl)borate). 相似文献

Synthesis of a series of monoorganobismuth dithiocarboxylate complexes, [RBi(S2CAr)2] (R = Me, Ph, tol; Ar = Ph, tol), has been reported. They have been characterized by elemental analyses and spectroscopic methods. Molecular structures of [RBi(S2Ctol)2] (R = Me or Ph) have been established by single crystal X-ray diffraction studies. The bismuth atom in these complexes adopts a square pyramidal configuration with the R group at the apical position. In the solid state, these complexes show supra-molecular association devoid of Bi?S secondary interactions. Thermolysis of [RBi(S2Ctol)2] (R = Me or Ph) in refluxing diphenylether yielded Bi2S3 nanocrystals which were characterized by XRD, EDAX and SEM. The complex [PhBi(S2Ctol)2] has been employed for deposition of thin films of Bi2S3 by AACVD. 相似文献

(Polypyrazolylborato)(benzonitrile) ruthenium(II) complexes [RuCl{BR(pz)3}(PhCN)2] (R = pz, H; pz = pyrazol-1-yl), prepared from trans-[RuCl2(PhCN)4] and K[BR(pz)3], were allowed to react with potassium 3,5-dimethyl-substituted polypyrazolylborate salt K[BH(3,5-Me2pz)3], and gave (pyrazolato)(pyrazole) species of [Ru{BR(pz)3}(3,5-Me2pz)(3,5-Me2pzH)2] {R = pz (1), H (2)}, respectively. Upon protonation with HBF4 (Et2O), the species 1 was converted to a fairly stable tris(pyrazole) derivative [Ru{B(pz)4}(3,5-Me2pzH)3]BF4 (3), which worked as a novel halogeno-anion receptor. Moreover, the complex [RuCl2(PhCN)4] was treated with K[BH(3,5-Me2-4-Brpz)3] in the presence of 3,5-dimethyl-4-bromopyrazole, 3,5-Me2-4-BrpzH, to afford [Ru{BH(3,5-Me2-4-Brpz)3}(3,5-Me2-4-Brpz)(3,5-Me2-4-BrpzH)2] and [Ru{BH(3,5-Me2-4-Brpz)3}(3,5-Me2-4-Brpz)(3,5-Me2-4-BrpzH)(PhCN)]. Single-crystal X-ray structural analyses were carried out for 1, 3 · CHCl3, [Ru{B(pz)4}(3,5-Me2pzH)2(OH2)]O3SC6H4CH3 · CH3OH, and [RuCl{B(pz)4}(3,5-Me2pzH)2] · CHCl3. 相似文献

The cytoplasmic Ca2+ concentration ([Ca2+]cyt) in resting cells in an equilibrium between several influx and efflux mechanisms. Here we address the question of whether
capacitative Ca2+ entry to some extent is active at resting conditions and therefore is part of processes that guarantee a constant [Ca2+]cyt. We measured changes of [Ca2+]cyt in RBL-1 cells with fluorometric techniques. An increase of the extracellular [Ca2+] from 1.3 mM to 5 mM induced an incrase in [Ca2+]cyt from 105±10 nM to 145±8.5 nM. This increase could be inhibited by 10 μM Gd3+, 10 μM La3+ or 50 μM 2-aminoethoxydiphenyl borate, blockers of capacitative Ca2+ entry. Application of those blockers to a resting cell in a standard extracellular solution (1.3 mM Ca2+) resulted in a decrease of [Ca2+]cyt from 105±10 nM to 88.5±10 nM with La3+, from 103±12 to 89±12 nM with Gd3+ and from 102±12 nM to 89.5±5 nM with 2-aminoethoxydiphenyl borate. From these data, we conclude that capacitative Ca2+ entry beside its function in Ca2+ signaling contributes to the regulation of resting [Ca2+]cyt. 相似文献

The [CO2] in the xylem of tree stems is typically two to three orders of magnitude greater than atmospheric [CO2]. In this study, xylem [CO2] was experimentally manipulated in saplings of sycamore (Platanus occidentalis L.) and sweetgum (Liquidambar styraciflua L.) by allowing shoots severed from their root systems to absorb water containing [CO2] ranging from 0.04% to 14%. The effect of xylem [CO2] on CO2 efflux to the atmosphere from uninjured and mechanically injured, i.e., wounded, stems was examined. In both wounded and unwounded stems, and in both species, CO2 efflux was directly proportional to xylem [CO2], and increased 5-fold across the range of xylem [CO2] produced by the [CO2] treatment. Xylem [CO2] explained 76–77% of the variation in pre-wound efflux. After wounding, CO2 efflux increased substantially but remained directly proportional to internal stem [CO2]. These experiments substantiated our previous finding that stem CO2 efflux was directly related to internal xylem [CO2] and expanded our observations to two new species. We conclude that CO2 transported in the xylem may confound measurements of respiration based on CO2 efflux to the atmosphere. This study also provided evidence that the rapid increase in CO2 efflux observed after tissues are excised or injured is likely the result of the rapid diffusion of CO2 from the xylem, rather than an actual increase in the rate of respiration of wounded tissues. 相似文献

A novel tin(II)-compound, bis(η2-N,O-2-[4,5-dimethyloxazolyl]-1,1,1-trifluoro-propen-2-olato)tin, SnII[(Me2C3NO)(CHCOCF3)]2 (1), was obtained by reacting Sn[N(SiMe3)2]2 with 2 M equivalents of the β-heteroarylalkenol, (Me2C3NO)(CHCOHCF3) (2). The molecular structures of ligand and the tin derivative were elucidated by single crystal X-ray diffraction and multi-nuclear NMR spectroscopic studies, which confirmed the monomeric nature and fourfold coordination of the tin(II) center with a pseudo-pyramidal geometry. The bidentate chelating mode of 2 imparted intriguingly high air stability to 1, which together with its high volatility make it an interesting precursor for the chemical vapor deposition (CVD) process. CVD of 1 on gold-coated Al2O3 substrates produced single crystalline SnO2 nanowires by vapor-liquid-solid growth mechanism. Transmission electron microscopy studies and X-ray diffraction data confirmed the high crystallinity of SnO2 nanowires possessing an average diameter of 90 nm. 相似文献

A new Wells-Dawson polyoxometalate-based compound, [CuII(2,2′-bipy)2(H2O)]3[CuI6(pz)6(P2W18O62)2] (2,2′-bipy = 2,2′-bipyridine, pz = pyrizine) (1), has been hydrothermally synthesized and characterized by routine physical methods. Compound 1 exhibits a [CuII(2,2′-bipy)2(H2O)]2+ complex-templated 3D (3,4)-connected framework with the topology of (63)(6284), which is built up by the cross-linking of porous P2W18-Cu layers and CuI-pz chains with Cu2 atoms as intersections. The transition-metal complex cation [CuII(2,2′-bipy)2(H2O)]2+ acts not only as a template locating in the voids of inorganic layers, but also as a charge-balance complex to make the 3D structure more steady. The electrochemistry property of compound 1 has also been discussed. 相似文献

We have investigated the kinetics of mitochondrial Ca2+ influx and efflux and their dependence on cytosolic [Ca2+] and [Na+] using low-Ca2+-affinity aequorin. The rate of Ca2+ release from mitochondria increased linearly with mitochondrial [Ca2+] ([Ca2+]M). Na+-dependent Ca2+ release was predominant al low [Ca2+]M but saturated at [Ca2+]M around 400 μM, while Na+-independent Ca2+ release was very slow at [Ca2+]M below 200 μM, and then increased at higher [Ca2+]M, perhaps through the opening of a new pathway. Half-maximal activation of Na+-dependent Ca2+ release occurred at 5-10 mM [Na+], within the physiological range of cytosolic [Na+]. Ca2+ entry rates were comparable in size to Ca2+ exit rates at cytosolic [Ca2+] ([Ca2+]c) below 7 μM, but the rate of uptake was dramatically accelerated at higher [Ca2+]c. As a consequence, the presence of [Na+] considerably reduced the rate of [Ca2+]M increase at [Ca2+]c below 7 μM, but its effect was hardly appreciable at 10 μM [Ca2+]c. Exit rates were more dependent on the temperature than uptake rates, thus making the [Ca2+]M transients to be much more prolonged at lower temperature. Our kinetic data suggest that mitochondria have little high affinity Ca2+ buffering, and comparison of our results with data on total mitochondrial Ca2+ fluxes indicate that the mitochondrial Ca2+ bound/Ca2+ free ratio is around 10- to 100-fold for most of the observed [Ca2+]M range and suggest that massive phosphate precipitation can only occur when [Ca2+]M reaches the millimolar range. 相似文献

The white homoleptic high-spin iron(II) complexes Fe[TpMe2,4Cl]2 (1) was isolated in quantitative yield from reaction mixtures containing 1 equiv of FeCl2(THF)1.5 and 2 equiv of K[TpMe2,4Cl] (TpMe2,4Cl = hydrotris[(4-chloro-3,5-dimethyl-pyrazolyl)]borate). Its purple low-spin iron(III) counterparts 1[O3SCF3] and 1[PF6] were synthesized and isolated in 85% yields upon treatment of 1 with 1 equiv of silver triflate and silver hexafluorophosphate, respectively. The three paramagnetic compounds are air and thermally stable as solids and in solution; they were characterized by elemental analyses, IR, magnetic susceptibility measurements, 1H NMR, and Mössbauer spectroscopy. In addition, 1[PF6] was authenticated by a single-crystal X-ray diffraction. The two scorpionate ligands are κ3-N,N′,N′′ ligated to the central FeIII ion, forming an almost perfect FeN6 octahedron with an average Fe-N bond distance of 1.9551(18) Å. In addition, complex 1 which oxidizes reversibly at E1/2 = 0.483 V/SCE (ΔEp = 94 mV), remains high-spin (S = 2) when the temperature is lowered to 2 K. 相似文献

Novel mononuclear Fe(II) complexes of tris(pyrazol-1-yl)methane [Fe{HC(pz)3}2]2+ with and p-sulfonatothiacalix[4]arene (TCAS4−) as counterions were obtained. The compounds were characterized by magnetic susceptibility method, IR and UV-Vis spectroscopy. The structure of [Fe{HC(pz)3}2]SiF6 has been analyzed by single-crystal X-ray diffraction. The 1H NMR spectroscopy measurements of [Fe{HC(pz)3}2]2(TСAS) in aqueous solution reveal the outer sphere inclusion of [Fe{HC(pz)3}2]2+ into the cyclophanic cavity of TCAS4−. The temperature induced spin-crossover 1А1 ⇔ 5Т2, accompanied by thermochromism, has been revealed from the temperature dependence of μeff and IR spectra for both complexes. The comparative analysis of magnetochemical and spectroscopy data elucidates the effect of the cyclophanic counterion on the physico-chemical properties of Fe(II) complex. 相似文献

Reactions of (NH4)2MS4 or (NH4)2MOS3 (M = Mo, W) with AgSCN and closo carborane diphosphine ligand 1,2-(PPh2)2-1,2-C2B10H10 (L) in CH2Cl2 yielded four heterobimetallic trinuclear Mo(W)-Ag-S clusters: [Ag2MoS4L2] (1), [Ag2WS4L2] (2), [Ag2MoOS3L2] (3) and [Ag2WS4L2] (4), respectively. All the new clusters have been characterized by elemental analysis, FT-IR, UV-Vis, 1H and 13C NMR spectroscopy and their molecular structures (except for 3) were further confirmed by single-crystal X-ray diffraction. X-ray crystal structure analysis showed that the closo carborane diphosphine ligand was coordinated bidentately to Ag(I) atom through its two phosphorus atoms, resulting in a stable five-member chelating ring between the diphosphine ligand and the metal. The coordination sphere of the central M atom, as well as all the Ag atoms, was tetrahedron. The skeletons of these clusters could be classified into two types: with (NH4)2MS4, the three metal atoms (two Ag atoms and one M atom) are in a linear conformation, while with (NH4)2MOS3, the conformation of the heterobimetallic trinuclear cluster is butterfly shaped. The luminescence properties of the clusters were investigated in CH2Cl2 solution at room temperature and for the first time the butterfly-shaped Ag-W-S cluster containing the Ag2WS4 core has been proved to show luminescence property. 相似文献

Glucagon induces intracellular Ca2+ ([Ca2+]i) elevation by stimulating glucagon receptor (GCGR). Such [Ca2+]i signaling plays important physiological roles, including glycogenolysis and glycolysis in liver cells and the survival of β-cells. Previous studies indicated that phospholipase C (PLC) might be involved in glucagon-mediated [Ca2+]i response. Other studies also debated whether cAMP accumulation mediated by GCGR/Gαs coupling contributes to [Ca2+]i elevation. But the exact mechanisms remain uncertain. In the present study, we found that glucagon induces [Ca2+]i elevation in HEK293 cells expressing GCGR. Removing extracellular Ca2+ did not affect glucagon-stimulated [Ca2+]i response. But depleting the intracellular Ca2+ store by thapsigargin completely inhibited glucagon-induced [Ca2+]i response. Experiments with forskolin and adenylyl cyclase inhibtor revealed that cAMP is not the cause of [Ca2+]i response. Further studies with Gαq/11 RNAi and pertussis toxin (PTX) indicated that both Gαq/11 and Gαi/o are involved. Combination of Gαq/11 RNAi and Gαi/o inhibition almost completely abolished glucagon-induced [Ca2+]i signaling. 相似文献

The heavier analogs of C2H2 have been studied at the B3LYP level for their μ and μ4-η2 coordination properties with the transition metals. Based on known alkyne compounds, transition metal fragments [W2(μ-NH)(Cp)2(Cl)2] and [Fe4(CO)12] have been chosen. The SBKJC relativistic effective core potentials and their associated basis sets were used on W, Fe, Sn and Pb, and the 6-31G(d) basis set was used on all other elements. All the complexes of Si2H2, Ge2H2, Sn2H2 and Pb2H2 are found to be local minima. The trans-twist nature of the ligand A2H2 (A = Si-Pb) is large in μ-coordinated complexes of W, and it is very small in μ4-η2 coordinated complexes of Fe. The electronic structure of these complexes was investigated using fragment molecular orbital method (FMO). 相似文献

The dihydrobis(3-carboxyethyl-5-methylpyrazolyl)borate ligand, BpCOOET,Me, reacts with divalent metals to yield complexes of general type [(BpCOOET,Me)2M], where M = Mn(II), Fe(II), Co(II), Ni(II), Zn(II), Cu(II), Pb(II) and Cd(II). All complexes have been fully characterized by elemental analyses and FT-IR in the solid state and by NMR (1H and 113Cd NMR) spectroscopy and electrospray ionization mass spectrometry in solution. A single crystal structural characterization is reported for [Cu(BpCOOET,Me)2] and [Zn(BpCOOET,Me)2]. In the two complexes, both metals are four-coordinated and they are only bound to the nitrogen atoms of the bis(pyrazolyl)borate ligand; however, while the environment of the copper atom is square planar, that of the zinc center shows a tetrahedral distorted conformation. 相似文献

Leaves developed at high irradiance (I) often have higher photosynthetic capacity than those developed at low I, while leaves developed at elevated CO2 concentration [CO2] often have reduced photosynthetic capacity compared with leaves developed at lower [CO2]. Because both high I and elevated [CO2] stimulate photosynthesis of developing leaves, their contrasting effects on photosynthetic capacity at maturity suggest that the extra photosynthate may be utilized differently depending on whether I or [CO2] stimulates photosynthesis. These experiments were designed to test whether relationships between photosynthetic income and the net accumulation of soluble protein in developing leaves, or relationships between soluble protein and photosynthetic capacity at full expansion differed depending on whether I or [CO2] was varied during leaf development. Soybean plants were grown initially with a photosynthetic photon flux density (PPFD) of 950 µmol m–2 s–1 and 350 µmol [CO2] mol–1, then exposed to [CO2] ranging from 135 to 1400 µmol mol–1 for the last 3 d of expansion of third trifoliolate leaves. These results were compared with experiments in which I was varied at a constant [CO2] of 350 µmol mol–1 over the same developmental period. Increases in area and dry mass over the 3 d were determined along with daily photosynthesis and respiration. Photosynthetic CO2 exchange characteristics and soluble protein content of leaves were determined at the end of the treatment periods. The increase in leaflet mass was about 28 % of the dry mass income from photosynthesis minus respiration, regardless of whether [CO2] or I was varied, except that very low I or [CO2] increased this percentage. Leaflet soluble protein per unit of area at full expansion had the same positive linear relationship to photosynthetic income whether [CO2] or I was varied. For variation in I, photosynthetic capacity varied directly with soluble protein per unit area. This was not the case for variation in [CO2]. Increasing [CO2] reduced photosynthetic capacity per unit of soluble protein by up to a factor of 2.5, and photosynthetic capacity exhibited an optimum with respect to growth [CO2]. Thus CO2 did not alter the relationship between photosynthetic income and the utilization of photosynthate in the net accumulation of soluble protein, but did alter the relationship between soluble protein content and photosynthetic characteristics in this species. 相似文献

New one-dimensional copper(I) coordination polymer [Cu2(μ-I)2(μ-(thio)2dapte)]n (1) {(thio)2dapte = N,N′-di-(thiophenecarbaldehyde)-1,2-di(o-aminophenylthio)ethane} involving a novel (NS)2 Schiff-base with a flexible spacer has been synthesized and structurally characterized by X-ray diffraction analysis. Each Cu(I) center adopts a distorted [CuN2S2] tetrahedron environment arising from two crystallographically equivalent (thio)2dapte Schiff-base ligands. Each ligand acts as N2S2-bis-chelating ligand with the nitrogen atoms of the two imine functions and from the two thioether atoms in anti-form leading to the dinuclear [Cu2(μ-(thio)2dapte)] groups. Such [Cu2] entities are bridged by two iodine anions [(μ-I)2] to form a neutral one-dimensional copper(I) coordination polymer (1). 相似文献
