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—H⋯Cl hydrogen bonds.
