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

Z. Hu and Z.-B. Zhu

Abstract: In the title complex, [La(C₆H₄NO₃)(C₂O₄)(H₂O)₂]_n, the La^III ion is coordinated by eight O atoms from two 2-oxidopyridinium-3-carboxylate ligands, two oxalate ligands and two water molecules in a distorted bicapped square-antiprismatic geometry. The carboxylate groups link adjacent La^III ions, forming two-dimensional layers that are further linked by N-HO and O-HO hydrogen bonds.
