Abstract

In the title compound, {[Cu(C7H3NO4)(H2O)3]·H2O}n, the CuII ion is bonded to three water molecules, one N,O-bidentate pyridine-2,3-dicarboxylate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO5 octahedral geometry. The bridging ligand results in an infinite chain. A network of O—H...O hydrogen bonds helps to establish the crystal structure.
