The structure described by MgCd crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded to nine equivalent Mg(1) and three equivalent Cd(1) atoms to form distorted MgMg9Cd3 cuboctahedra that share corners with six equivalent Mg(1)Mg9Cd3 cuboctahedra, corners with twelve equivalent Cd(1)Mg3Cd9 cuboctahedra, edges with six equivalent Cd(1)Mg3Cd9 cuboctahedra, edges with twelve equivalent Mg(1)Mg9Cd3 cuboctahedra, faces with eight equivalent Cd(1)Mg3Cd9 cuboctahedra, and faces with twelve equivalent Mg(1)Mg9Cd3 cuboctahedra. Cd(1) is bonded to three equivalent Mg(1) and nine equivalent Cd(1) atoms to form distorted CdMg3Cd9 cuboctahedra that share corners with six equivalent Cd(1)Mg3Cd9 cuboctahedra, corners with twelve equivalent Mg(1)Mg9Cd3 cuboctahedra, edges with six equivalent Mg(1)Mg9Cd3 cuboctahedra, edges with twelve equivalent Cd(1)Mg3Cd9 cuboctahedra, faces with eight equivalent Mg(1)Mg9Cd3 cuboctahedra, and faces with twelve equivalent Cd(1)Mg3Cd9 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
