Os2HgSb crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to one Os(2) and one Sb(1) atom. The Os(1)-Os(2) bond length is 2.42 Å. The Os(1)-Sb(1) bond length is 2.51 Å. In the second Os site, Os(2) is bonded to one Os(1), six equivalent Os(2), and one Hg(1) atom to form a mixture of distorted edge and corner-sharing OsHgOs7 hexagonal bipyramids. All Os(2)-Os(2) bond lengths are 3.07 Å. The Os(2)-Hg(1) bond length is 3.24 Å. Hg(1) is bonded in a single-bond geometry to one Os(2) and one Sb(1) atom. The Hg(1)-Sb(1) bond length is 0.73 Å. Sb(1) is bonded in a single-bond geometry to one Os(1) and one Hg(1) atom.
