Al Sb Sb Os
OsAlSb2 crystallizes in the monoclinic Cm space group. Os(1) is bonded in a single-bond geometry to one Al(1) and three equivalent Sb(1) atoms. The Os(1)-Al(1) bond length is 1.05 Å. There is one shorter (2.92 Å) and two longer (3.31 Å) Os(1)-Sb(1) bond lengths. Al(1) is bonded in a distorted single-bond geometry to one Os(1) and one Sb(2) atom. The Al(1)-Sb(2) bond length is 2.18 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to three equivalent Os(1), one Sb(2), and four equivalent Sb(1) atoms. The Sb(1)-Sb(2) bond length is 3.06 Å. All Sb(1)-Sb(1) bond lengths are 3.23 Å. In the second Sb site, Sb(2) is bonded in a 1-coordinate geometry to one Al(1) and one Sb(1) atom.
