Synthesis and Crystal Structure of a New Two-Dimensional Coordination Polymer, {[Co~(II)(imbz)_2].H_2O}_n [imbz~- = 4'-(Imidazol-l-ylmethyl)benzoate Anion]

摘要

A new coordination polymer, {[Co~(II)(imbz)_2].H_2O}_n [imbz~- = 4'-(imidzol-l-ylmethyl)benzoate anion] was synthesized and characterized by X-ray crystallography. Each Co(II) atom is coordinated by four imbz ligands, two of which using N atoms of imidazole and theother two using O atoms of benzoate, and each imbz ligand connects two Co(II) to generate an infinite 2D network. The crystal water molecules locate in the voids of two adjacent layers through C-H---O and O-H---O hydrogen bonds.
