Tetra-[mu]-acetato-[kappa]8O:O'-bis­[(pyridine-2-carbo­nitrile-[kappa]N1)copper(II)]

M. Luo, L. Wang and J.-C. Zhang

Abstract: The title binuclear compound, [Cu2(CH3COO)4(C6H4N2)2], lies about an inversion center, with the CuII cation bridged by four acetate anions and coordinated by a pyridine N atom in a distorted square-pyramidal geometry. The Cu...Cu distance is 2.5997 (15) Å. In the crystal, mol­ecules are linked by weak C-H...O and C-H...N hydrogen bonds into a three-dimensional supra­molecular architecture. The crystal studied was a non-merohedral twin with a minor twin component of 4.1 (1)%.
