In the title compound, [Cu 2 Cl 4 (C 6 H 10 N 8 ) 2 ] n , the ligand has C 2 symmetry, and the Cu and Cl atoms lie on a mirror plane. The coordination polyhedron of the Cu atom is a distorted square pyramid, with the basal positions occupied by two N atoms from two different ligands [Cu-N = 2.0407 (18) A] and by the two Cl atoms [Cu-Cl = 2.2705 (8) and 2.2499 (9) A], and the apical position occupied by a Cl atom [Cu-Cl=2.8154(9) A] that belongs to the basal plane of a neighbouring Cu atom. The [CuCl 2 (C 6 H 10 N 8 )] 2 units form infinite chains extending along the a axis via the Cl atoms. Intermolecular C-H...Cl contacts [C...Cl = 3.484 (2) A] are also present in the chains. The chains are linked together by intermolecular C-H...N interactions [C...N = 3.314 (3) A].
