Abstract: The asymmetric unit of the title polymeric complex, [Cd2(C13H7NO4)(OH)2]n, consists of two independent CdII atoms, one 5-(4-carboxyphenyl)pyridine-2-carboxylate ligand and two hydroxy groups. One CdII atom is six-coordinated by two O atoms from two ligand molecules and by four 3-OH groups in a distorted trigonal-prismatic geometry. The other is five-coordinated by one N and two O atoms from two ligands and by two 3-OH groups, forming a distorted square-pyramidal geometry. The two independent CdII atoms are connected by the ligand molecules and the OH groups into a three-dimensional framework. O-HO hydrogen bonds between the OH groups and the carboxylate O atoms are observed.
