The material structure described by MgCd2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded to ten equivalent Cd(1) atoms to form distorted MgCd10 cuboctahedra that share corners with eighteen equivalent Cd(1)Mg5Cd7 cuboctahedra, edges with six equivalent Cd(1)Mg5Cd7 cuboctahedra, edges with twelve equivalent Mg(1)Cd10 cuboctahedra, faces with four equivalent Mg(1)Cd10 cuboctahedra, and faces with twelve equivalent Cd(1)Mg5Cd7 cuboctahedra. Cd(1) is bonded to five equivalent Mg(1) and seven equivalent Cd(1) atoms to form distorted CdMg5Cd7 cuboctahedra that share corners with nine equivalent Mg(1)Cd10 cuboctahedra, corners with nine equivalent Cd(1)Mg5Cd7 cuboctahedra, edges with three equivalent Mg(1)Cd10 cuboctahedra, edges with fourteen equivalent Cd(1)Mg5Cd7 cuboctahedra, faces with six equivalent Mg(1)Cd10 cuboctahedra, and faces with thirteen equivalent Cd(1)Mg5Cd7 cuboctahedra. is represented by the CIF card [CIF]
