Hf2CdZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Hf2CdZn clusters. Hf(1) is bonded in a single-bond geometry to one Zn(1) atom. The Hf(1)-Zn(1) bond length is 0.73 Å. Cd(1) is bonded in a single-bond geometry to one Zn(1) atom. The Cd(1)-Zn(1) bond length is 0.75 Å. Zn(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Hf(1) and one Cd(1) atom.
