In the title polymer, [Cu(C 7 H 3 NO 4 )(H 2 O) 2 ] n , the Cu II ion is pentacoordinated and exhibits a distorted square-pyramidal environment formed by one N atom and two O atoms from pyridine-2,4-dicarboxylate ligands and two O atoms from coordinated water molecules. Each pyridine-2,4-dicarboxyla
