In the title compound, [Cd4Cl8(C6H16N2)4], the Cd2+ cations and Cl− anions form M4Cl8 clusters with six of the Cl− ions bridging Cd2+ cations and two being pendant. Each Cd2+ cation has distorted octahedral coordination completed by four Cl− ions and two N atoms of the asymmetrical bidentate amino ligand. The cluster consists of pairs of face-sharing hexahedra linked by a shared edge.
