Li Li Sn Os
Li2OsSn crystallizes in the triclinic P1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted T-shaped geometry to one Li(2), one Os(1), and one Sn(1) atom. The Li(1)-Li(2) bond length is 1.13 Å. The Li(1)-Os(1) bond length is 2.32 Å. The Li(1)-Sn(1) bond length is 2.60 Å. In the second Li site, Li(2) is bonded in a 5-coordinate geometry to one Li(1), two equivalent Os(1), and two equivalent Sn(1) atoms. There is one shorter (2.42 Å) and one longer (2.48 Å) Li(2)-Os(1) bond length. There is one shorter (2.12 Å) and one longer (2.61 Å) Li(2)-Sn(1) bond length. Os(1) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Li(2), and one Sn(1) atom. The Os(1)-Sn(1) bond length is 1.86 Å. Sn(1) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Li(2), and one Os(1) atom.
