ScOs2Al crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a single-bond geometry to four equivalent Os(1) and one Al(1) atom. There are a spread of Sc(1)-Os(1) bond distances ranging from 2.74-3.24 Å. The Sc(1)-Al(1) bond length is 0.53 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 9-coordinate geometry to four equivalent Sc(1), one Os(2), and four equivalent Os(1) atoms. The Os(1)-Os(2) bond length is 2.21 Å. All Os(1)-Os(1) bond lengths are 3.15 Å. In the second Os site, Os(2) is bonded in a 5-coordinate geometry to one Os(1) and four equivalent Al(1) atoms. There are a spread of Os(2)-Al(1) bond distances ranging from 2.39-2.95 Å. Al(1) is bonded in a single-bond geometry to one Sc(1) and four equivalent Os(2) atoms.
