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 CuCu distance is 2.5997 (15) Å. In the crystal, molecules are linked by weak C-HO and C-HN 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)%.
