Abstract: In the title two-dimensional coordination polymer, [Cu(C₉H₆O₅)(C₇H₆N₂)]_n, each Cu^II 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.
