A two-dimensional coordination polymer containing copper(II): poly[[(1H-benzimidazole-N3)copper(II)]-3-3-carboxylatophenoxyacetato-4O,O′:O′′:O′′′]
In the title two-dimensional coordination polymer, [Cu(C9H6O5)(C7H6N2)]n, each CuII atom exists in a distorted square-pyramidal coordination environment, defined by one N atom from the terminal benzimidazole molecule and four carboxyl O atoms derived from three different 3-carboxylatophenoxyacetate (3-CPOA) dianions. The tetradentate 3-CPOA ligand forms three bonds to adjacent Cu atoms to form chains that are linked to neighboring chains, via a fourth Cu—O bond, so as to form a layer structure that is further stabilized by hydrogen bonds.
