Hf Hf Ga Ga Os
Hf2OsGa2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Hf2OsGa2 clusters. Hf(1) is bonded in a single-bond geometry to one Os(1) and one Ga(1) atom. The Hf(1)-Os(1) bond length is 0.18 Å. The Hf(1)-Ga(1) bond length is 0.59 Å. Os(1) is bonded in a 2-coordinate geometry to two equivalent Hf(1) and one Ga(2) atom. The Os(1)-Ga(2) bond length is 0.82 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to two equivalent Hf(1) atoms. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Os(1) atom.
