The material structure described by Mg2OsH6 crystallizes in the cubic Fm-3m space group. Mg(1) is bonded to twelve equivalent H(1) atoms to form MgH12 cuboctahedra that share corners with twelve equivalent Mg(1)H12 cuboctahedra, faces with six equivalent Mg(1)H12 cuboctahedra, and faces with four equivalent Os(1)H6 octahedra. Os(1) is bonded to six equivalent H(1) atoms to form OsH6 octahedra that share faces with eight equivalent Mg(1)H12 cuboctahedra. H(1) is bonded to four equivalent Mg(1) and one Os(1) atom to form a mixture of face, corner, and edge-sharing HMg4Os square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
