Abstract: | A novel 2-D metal-organic coordination polymer [Ni0.5(apddica)(H2O)] · H2O 1 (Hapddica=2-(4-Amino-phenyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid) has been hydrothermally synthesized and structurally characterized by element analyses, IR and XPS spectra, TG analyses and single crystal X-ray diffraction. Crystal data: C15H13N2Ni0.5O6, monoclinic, P2(1)/c, a=12.181(2) Å, b=7.9392(6) Å, c=14.835(3) Å, β=94.25(3) °, V=1430(75) Å3, Z=4. Compound 1 exhibits a novel 2-D double-layers network based on apddica and Ni center. It is noteworthy that new ligand Hapddica was first prepared with hydrothermal technique involving in situ ligand synthesis and used for constructing coordination polymers. There are unusual parallelogram tunnels along a-axis in which the dissociative water molecules filled in. The magnetic property of compound has been studied. |
