Hf Cd Cd Cu
HfCuCd2 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one HfCuCd2 cluster. Hf(1) is bonded in a single-bond geometry to one Cu(1) and one Cd(1) atom. The Hf(1)-Cu(1) bond length is 0.17 Å. The Hf(1)-Cd(1) bond length is 2.24 Å. Cu(1) is bonded in a single-bond geometry to one Hf(1) and one Cd(2) atom. The Cu(1)-Cd(2) bond length is 2.08 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Hf(1) atom. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Cu(1) atom.
