HfPtCl2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfPtCl2 clusters. Hf(1) is bonded in a 2-coordinate geometry to one Cl(1) and one Cl(2) atom. The Hf(1)-Cl(1) bond length is 1.96 Å. The Hf(1)-Cl(2) bond length is 1.72 Å. Pt(1) is bonded in a single-bond geometry to one Cl(2) atom. The Pt(1)-Cl(2) bond length is 1.30 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Hf(1) atom. In the second Cl site, Cl(2) is bonded in a distorted bent 120 degrees geometry to one Hf(1) and one Pt(1) atom.
