Os2RuAl crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 13-coordinate geometry to one Os(2), four equivalent Os(1), four equivalent Ru(1), and four equivalent Al(1) atoms. The Os(1)-Os(2) bond length is 2.48 Å. All Os(1)-Os(1) bond lengths are 2.81 Å. There are a spread of Os(1)-Ru(1) bond distances ranging from 2.04-2.67 Å. There are a spread of Os(1)-Al(1) bond distances ranging from 2.56-3.09 Å. In the second Os site, Os(2) is bonded in a 12-coordinate geometry to one Os(1), four equivalent Os(2), four equivalent Ru(1), and three equivalent Al(1) atoms. All Os(2)-Os(2) bond lengths are 2.81 Å. There are a spread of Os(2)-Ru(1) bond distances ranging from 2.04-2.67 Å. There is one shorter (3.08 Å) and two longer (3.31 Å) Os(2)-Al(1) bond lengths. Ru(1) is bonded in a 8-coordinate geometry to four equivalent Os(1) and four equivalent Os(2) atoms. Al(1) is bonded in a 1-coordinate geometry to three equivalent Os(2) and four equivalent Os(1) atoms.
