Materials Data on Mg2OsS6 by Materials Project
Mg2OsS6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mg2+ is bonded to twelve equivalent S2- atoms to form MgS12 cuboctahedra that share corners with twelve equivalent MgS12 cuboctahedra, faces with six equivalent MgS12 cuboctahedra, and faces with four equivalent OsS6 octahedra. All Mg–S bond lengths are 3.14 Å. Os8+ is bonded to six equivalent S2- atoms to form OsS6 octahedra that share faces with eight equivalent MgS12 cuboctahedra. All Os–S bond lengths are 2.32 Å. S2- is bonded in a 1-coordinate geometry to four equivalent Mg2+ and one Os8+ atom.
