catena-Poly[[bis(3-pyridylmethanol-κN)copper(II)]-μ-oxalato-1κ2 O 1,O 2:2κ2 O 1′,O 2′]

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.
