title: Tetra-μ-acetato-κ(8) O:O'-bis-[(pyridine-2-carbo-nitrile-κN (1))copper(II)].
abstract: The title binuclear compound, [Cu2(CH3COO)4(C6H4N2)2], lies about an inversion center, with the Cu(II) 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, mol-ecules are linked by weak C-H⋯O and C-H⋯N hydrogen bonds into a three-dimensional supra-molecular architecture. The crystal studied was a non-merohedral twin with a minor twin component of 4.1 (1)%.
