OsNi2Sn crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 13-coordinate geometry to four equivalent Os(1), four equivalent Ni(1), four equivalent Ni(2), and one Sn(1) atom. All Os(1)-Os(1) bond lengths are 2.82 Å. There are a spread of Os(1)-Ni(1) bond distances ranging from 2.72-3.21 Å. There are a spread of Os(1)-Ni(2) bond distances ranging from 2.72-3.21 Å. The Os(1)-Sn(1) bond length is 3.01 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 1-coordinate geometry to four equivalent Os(1), one Ni(2), and three equivalent Sn(1) atoms. The Ni(1)-Ni(2) bond length is 2.80 Å. There is one shorter (1.82 Å) and two longer (2.19 Å) Ni(1)-Sn(1) bond lengths. In the second Ni site, Ni(2) is bonded in a 13-coordinate geometry to four equivalent Os(1), one Ni(1), four equivalent Ni(2), and four equivalent Sn(1) atoms. All Ni(2)-Ni(2) bond lengths are 2.82 Å. There are a spread of Ni(2)-Sn(1) bond distances ranging from 2.55-3.07 Å. Sn(1) is bonded in a 3-coordinate geometry to one Os(1), three equivalent Ni(1), and four equivalent Ni(2) atoms.
