OsSnSi is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one OsSnSi cluster. Os(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one Si(1) atom. The Os(1)-Sn(1) bond length is 0.87 Å. The Os(1)-Si(1) bond length is 0.66 Å. Sn(1) is bonded in a single-bond geometry to one Os(1) atom. Si(1) is bonded in a single-bond geometry to one Os(1) atom.
