Cr2OsIn crystallizes in the monoclinic Cm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 9-coordinate geometry to one Cr(2), four equivalent Cr(1), and four equivalent Os(1) atoms. The Cr(1)-Cr(2) bond length is 2.77 Å. All Cr(1)-Cr(1) bond lengths are 2.79 Å. There are a spread of Cr(1)-Os(1) bond distances ranging from 2.87-3.40 Å. In the second Cr site, Cr(2) is bonded in a 3-coordinate geometry to one Cr(1) and three equivalent In(1) atoms. There is one shorter (1.78 Å) and two longer (2.20 Å) Cr(2)-In(1) bond lengths. Os(1) is bonded in a single-bond geometry to four equivalent Cr(1) and one In(1) atom. The Os(1)-In(1) bond length is 1.53 Å. In(1) is bonded in a 1-coordinate geometry to three equivalent Cr(2) and one Os(1) atom.
