The structure described by MgCd crystallizes in the hexagonal P-6m2 space group. Mg(1) is bonded to six equivalent Mg(1) and six equivalent Cd(1) atoms to form distorted MgMg6Cd6 cuboctahedra that share corners with eighteen equivalent Mg(1)Mg6Cd6 cuboctahedra, edges with six equivalent Mg(1)Mg6Cd6 cuboctahedra, edges with twelve equivalent Cd(1)Mg6Cd6 cuboctahedra, faces with eight equivalent Mg(1)Mg6Cd6 cuboctahedra, and faces with twelve equivalent Cd(1)Mg6Cd6 cuboctahedra. Cd(1) is bonded to six equivalent Mg(1) and six equivalent Cd(1) atoms to form distorted CdMg6Cd6 cuboctahedra that share corners with eighteen equivalent Cd(1)Mg6Cd6 cuboctahedra, edges with six equivalent Cd(1)Mg6Cd6 cuboctahedra, edges with twelve equivalent Mg(1)Mg6Cd6 cuboctahedra, faces with eight equivalent Cd(1)Mg6Cd6 cuboctahedra, and faces with twelve equivalent Mg(1)Mg6Cd6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
