Poly[diaqua([mu]-oxalato)([mu]-2-oxidopyridinium-3-carboxylato)praseodymium(III)]

Y.-J. Xu, X.-X. Yang and H.-B. Zhao

Abstract: In the title complex, [Pr(C6H4NO3)(C2O4)(H2O)2]n, each PrIII ion is coordinated by eight O atoms from two 2-oxynicotinate ligands, two oxalate ligands and two water molecules, displaying a distorted bicapped square-antiprismatic geometry. The carboxylate groups link adjacent praseodymium metal centres, forming layers parallel to the bc plane. The crystal packing is stabilized by intermolecular O-H...O and N-H...O hydrogen bonds.
