CuCd(Al)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one dialuminium molecule and one CuCd cluster. In the CuCd cluster, Cu(1) is bonded in a 1-coordinate geometry to one Cd(1) atom. The Cu(1)-Cd(1) bond length is 1.48 Å. Cd(1) is bonded in a single-bond geometry to one Cu(1) atom.
