Synthesis and crystal structure of a new one-dimensional chain coordination polymer, [Co(imbz)2(H2O)2]n[imbz=4′-(imidazol-1-ylmethyl) benzoate anion

A new coordination polymer [Co(imbz)(2)(H2O)(2)](n). [imbz = 4 '-(imidazol-1-ylmethyl) benzoate anion] was synthesized and characterized by x-ray crystallography. The title complex crystallizes in monoclinic, space group P2(1/c), a = 10.910(2), b = 8.8720(18), c = 11.252(2) Angstrom, beta = 92.20 (3)degrees, V = 1088.3 (4) Angstrom (3), Z = 2, D-c = 1.518g . cm(-3), mu = 0.836 cm(-1), F(000) = 514, R = 0.0679, w R = 0.1710. Each Co (II) atom has a distorted octahedral coordination geometry and is six-coordinated by two water molecules and four imbz ligands. Each imbz ligand connects two Co (II) to generate an infinite 1D twisted chain structure.
