Hf Hf Sn Pt
Hf2PtSn crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one Hf2PtSn cluster. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Pt(1) atom. The Hf(1)-Pt(1) bond length is 1.48 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Sn(1) atom. The Hf(2)-Sn(1) bond length is 0.67 Å. Pt(1) is bonded in a distorted bent 150 degrees geometry to one Hf(1) and one Sn(1) atom. The Pt(1)-Sn(1) bond length is 0.98 Å. Sn(1) is bonded in a distorted bent 120 degrees geometry to one Hf(2) and one Pt(1) atom.
