The material described by MgCuZn crystallizes in the orthorhombic Imma space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1), six equivalent Cu(1), and six equivalent Zn(1) atoms. Cu(1) is bonded to six equivalent Mg(1), two equivalent Cu(1), and four equivalent Zn(1) atoms to form CuMg6Zn4Cu2 cuboctahedra that share corners with eight equivalent Zn(1)Mg6Zn2Cu4 cuboctahedra, corners with ten equivalent Cu(1)Mg6Zn4Cu2 cuboctahedra, edges with six equivalent Cu(1)Mg6Zn4Cu2 cuboctahedra, faces with six equivalent Cu(1)Mg6Zn4Cu2 cuboctahedra, and faces with twelve equivalent Zn(1)Mg6Zn2Cu4 cuboctahedra. Zn(1) is bonded to six equivalent Mg(1), four equivalent Cu(1), and two equivalent Zn(1) atoms to form ZnMg6Zn2Cu4 cuboctahedra that share corners with eight equivalent Cu(1)Mg6Zn4Cu2 cuboctahedra, corners with ten equivalent Zn(1)Mg6Zn2Cu4 cuboctahedra, edges with six equivalent Zn(1)Mg6Zn2Cu4 cuboctahedra, faces with six equivalent Zn(1)Mg6Zn2Cu4 cuboctahedra, and faces with twelve equivalent Cu(1)Mg6Zn4Cu2 cuboctahedra. is represented by the CIF file [CIF]
