The material described by MgOs is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Os(1) atoms to form distorted MgMg4Os8 cuboctahedra that share corners with eight equivalent Os(1)Mg8Os4 cuboctahedra, corners with ten equivalent Mg(1)Mg4Os8 cuboctahedra, edges with six equivalent Mg(1)Mg4Os8 cuboctahedra, edges with twelve equivalent Os(1)Mg8Os4 cuboctahedra, faces with eight equivalent Os(1)Mg8Os4 cuboctahedra, and faces with twelve equivalent Mg(1)Mg4Os8 cuboctahedra.
