Hf Hf Sn Os
Hf2OsSn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf2OsSn cluster. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a distorted single-bond geometry to one Sn(1) atom. The Hf(1)-Sn(1) bond length is 2.07 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Os(1) atom. The Hf(2)-Os(1) bond length is 0.54 Å. Os(1) is bonded in a distorted single-bond geometry to one Hf(2) and one Sn(1) atom. The Os(1)-Sn(1) bond length is 1.33 Å. Sn(1) is bonded in a bent 150 degrees geometry to one Hf(1) and one Os(1) atom.
