HfReSn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfReSn clusters. Hf(1) is bonded in a linear geometry to one Re(1) and one Sn(1) atom. The Hf(1)-Re(1) bond length is 0.36 Å. The Hf(1)-Sn(1) bond length is 0.93 Å. Re(1) is bonded in a single-bond geometry to one Hf(1) atom. Sn(1) is bonded in a distorted single-bond geometry to one Hf(1) atom.
