Tetra-μ-acetato-κ⁸ O:O′-bis[(pyridine-2-carbonitrile-κN ¹)copper(II)]

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)%.
