Ga Sn Os Os
Os2GaSn crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 9-coordinate geometry to one Os(2), four equivalent Os(1), and four equivalent Sn(1) atoms. The Os(1)-Os(2) bond length is 2.04 Å. All Os(1)-Os(1) bond lengths are 3.16 Å. There are a spread of Os(1)-Sn(1) bond distances ranging from 2.84-3.34 Å. In the second Os site, Os(2) is bonded in a 5-coordinate geometry to one Os(1) and four equivalent Ga(1) atoms. There are a spread of Os(2)-Ga(1) bond distances ranging from 2.25-2.87 Å. Ga(1) is bonded in a distorted single-bond geometry to four equivalent Os(2) and one Sn(1) atom. The Ga(1)-Sn(1) bond length is 0.88 Å. Sn(1) is bonded in a single-bond geometry to four equivalent Os(1) and one Ga(1) atom.
