The material structure described by MgMnCd6O8 is alpha Po-derived structured and crystallizes in the cubic Fm-3m space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and edges with twelve equivalent Cd(1)O6 octahedra. The corner-sharing octahedra are not tilted. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and edges with twelve equivalent Cd(1)O6 octahedra. The corner-sharing octahedra are not tilted. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with eight equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mn(1), and four equivalent Cd(1) atoms to form OMgMnCd4 octahedra that share corners with six equivalent O(1)MgMnCd4 octahedra, edges with four equivalent O(2)Cd6 octahedra, and edges with eight equivalent O(1)MgMnCd4 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to six equivalent Cd(1) atoms to form OCd6 octahedra that share corners with six equivalent O(2)Cd6 octahedra and edges with twelve equivalent O(1)MgMnCd4 octahedra. The corner-sharing octahedra are not tilted. In the third O site, O(1) is bonded to one Mg(1), one Mn(1), and four equivalent Cd(1) atoms to form OMgMnCd4 octahedra that share corners with six equivalent O(1)MgMnCd4 octahedra, edges with four equivalent O(2)Cd6 octahedra, and edges with eight equivalent O(1)MgMnCd4 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
