Ca Sn Os Os
CaOs2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CaOs2Sn cluster. Ca(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Ca(1)-Os(1) bond length is 1.79 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in an L-shaped geometry to one Ca(1) and one Sn(1) atom. The Os(1)-Sn(1) bond length is 1.14 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Sn(1) atom. The Os(2)-Sn(1) bond length is 1.14 Å. Sn(1) is bonded in a distorted linear geometry to one Os(1) and one Os(2) atom.
