| Abstract: | From the interaction between azole-type ligands L and AgX (X = NO3 or ClO4) or AgX(PPh3)n] (X = Cl, n = 3; X = MeSO3, n = 2), new ionic mononuclear Ag(L)2]X and Ag(PPh3)3L]X] or neutral mono-(Ag(PPh3)nL(X)]) or di-nuclear ({Ag(PPh3)(L)(μ-X)}2]) complexes have been obtained which have been characterized through elemental analysis, conductivity measurements, IR, 1H NMR and, in some cases, also by 31P{1H} NMR spectroscopy, and single-crystal X-ray studies. Stoichiometries and molecular structures are dependent on the nature of the azole (steric hindrance and basicity), of the counter ion, and on the number of the P-donor ligands in the starting reactants. Solution data are consistent with partial dissociation of the complexes, occurring through breaking of both Ag-N and Ag-P bonds. |
