Hf2Sn(HfSn)2 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Hf2Sn clusters and two HfSn clusters. In each Hf2Sn cluster, there are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Sn(2) atom. The Hf(1)-Sn(2) bond length is 1.52 Å. In the second Hf site, Hf(3) is bonded in a single-bond geometry to one Sn(2) atom. The Hf(3)-Sn(2) bond length is 0.02 Å. Sn(2) is bonded in a distorted linear geometry to one Hf(1) and one Hf(3) atom. In each HfSn cluster, there are two inequivalent Hf sites. In the first Hf site, Hf(2) is bonded in a linear geometry to one Sn(1) and one Sn(3) atom. The Hf(2)-Sn(1) bond length is 1.57 Å. The Hf(2)-Sn(3) bond length is 1.52 Å. In the second Hf site, Hf(4) is bonded in a single-bond geometry to one Sn(3) atom. The Hf(4)-Sn(3) bond length is 0.02 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Hf(2) atom. In the second Sn site, Sn(3) is bonded in a distorted linear geometry to one Hf(2) and one Hf(4) atom.
