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].
