Si Sb Os
OsSiSb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsSiSb clusters. Os(1) is bonded in a single-bond geometry to one Sb(1) atom. The Os(1)-Sb(1) bond length is 0.22 Å. Si(1) is bonded in a single-bond geometry to one Sb(1) atom. The Si(1)-Sb(1) bond length is 1.56 Å. Sb(1) is bonded in a distorted single-bond geometry to one Os(1) and one Si(1) atom.
