In the title compound, [Cu2Cl4(C16H32N4)]n, the central CuII anion of the macrocyclic complex cation is weakly linked to two Cl atoms of the tetrachloridocuprate anion with Cu—Cl distances of 3.008 (3) and 3.220 (3) Å, respectively, forming a chain parallel to [10-1]. The geometry of the Cu–macrocyclic complex is distorted octahedral with the bridging Cl atoms occupying the axial position at an angle of 173.44 (7)° about the central CuII atom. The tetrachloridocuprate anion adopts a distorted tetrahedral geometry. In the crystal, the chain is stabilized by intra- and intermolecular N—HCl hydrogen bonds.
