OsHg crystallizes in the hexagonal P-6m2 space group. Os(1) is bonded to six equivalent Os(1) and six equivalent Hg(1) atoms to form OsHg6Os6 cuboctahedra that share corners with eighteen equivalent Os(1)Hg6Os6 cuboctahedra, edges with six equivalent Os(1)Hg6Os6 cuboctahedra, edges with twelve equivalent Hg(1)Hg6Os6 cuboctahedra, faces with eight equivalent Os(1)Hg6Os6 cuboctahedra, and faces with twelve equivalent Hg(1)Hg6Os6 cuboctahedra. Hg(1) is bonded to six equivalent Os(1) and six equivalent Hg(1) atoms to form HgHg6Os6 cuboctahedra that share corners with eighteen equivalent Hg(1)Hg6Os6 cuboctahedra, edges with six equivalent Hg(1)Hg6Os6 cuboctahedra, edges with twelve equivalent Os(1)Hg6Os6 cuboctahedra, faces with eight equivalent Hg(1)Hg6Os6 cuboctahedra, and faces with twelve equivalent Os(1)Hg6Os6 cuboctahedra.
