HfClZnCl is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfCl clusters and two ZnCl clusters. In each HfCl cluster, Hf(1) is bonded in a single-bond geometry to one Cl(1) atom. The Hf(1)-Cl(1) bond length is 0.60 Å. Cl(1) is bonded in a single-bond geometry to one Hf(1) atom. In each ZnCl cluster, Zn(1) is bonded in a distorted single-bond geometry to one Cl(2) atom. The Zn(1)-Cl(2) bond length is 2.29 Å. Cl(2) is bonded in a single-bond geometry to one Zn(1) atom.
