Sn Sn Os Se
OsSn2Se crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one OsSn2Se cluster. Os(1) is bonded in a distorted single-bond geometry to one Sn(2) atom. The Os(1)-Sn(2) bond length is 1.91 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.80 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Os(1), one Sn(1), and one Se(1) atom. The Sn(2)-Se(1) bond length is 0.54 Å. Se(1) is bonded in a single-bond geometry to one Sn(2) atom.
