In the title compound, [Cu(C2O4)(C6H7NO)2] n , the CuII atom is six-coordinated in a slightly deformed elongated octahedral arrangement and the 3-(hydroxymethyl)pyridine ligand, surprisingly, acts as a monodentate ligand coordinated only through the N atom of the pyridine ring. The oxalate ligands, on inversion centres, bridge the metal ions, forming infinite chains. The chains are linked by intermolecular O—H...O hydrogen bonds into a three-dimensional network.
