Polymeric aqua(₄-maleato-⁴O)pyridylnickel(II)

Abstract: The title nickel coordination polymer, [Ni(C₄H₂O₄)(C₅H₅N)(H₂O)]_n, has been obtained from the reaction of NiCl₂·6H₂O with disodium maleate and pyridine in an alcohol-water solution. Single-crystal X-ray analysis revealed that each Ni atom contains an approximately octahedral coordination environment in the compound with the maleate ligand in a novel coordination mode. The molecule has mirror symmetry. O-HO hydrogen bonds exist in the corrugated two-dimensional structure; this is further extended into a three-dimensional framework via strong non-classical C-HO interactions between adjacent layers.
