Hg Os Rh
OsRhHg crystallizes in the monoclinic Cm space group. Os(1) is bonded in a single-bond geometry to one Rh(1) and one Hg(1) atom. The Os(1)-Rh(1) bond length is 3.17 Å. The Os(1)-Hg(1) bond length is 0.58 Å. Rh(1) is bonded in a 6-coordinate geometry to one Os(1), four equivalent Rh(1), and one Hg(1) atom. All Rh(1)-Rh(1) bond lengths are 2.83 Å. The Rh(1)-Hg(1) bond length is 2.75 Å. Hg(1) is bonded in a single-bond geometry to one Os(1) and one Rh(1) atom.
