catena-Poly[[bis(pyridine-κN)nickel(II)]-μ-oxalato-κ4O1,O2:O1′,O2′]

Abstract

The title compound, [Ni(C2O4)(C5H5N)2]n, was synthesized under hydro(solvo)thermal conditions. The NiII atom, lying on a twofold rotation axis, has an octahedral coordination geometry involving two N atoms from two pyridine ligands and four O atoms from two oxalate ligands. The Ni atoms are connected by the tetradentate bridging oxalate ligands into a one-dimensional zigzag chain.
