AuCuZn2 crystallizes in the orthorhombic Pmmn space group. Au(1) is bonded to four equivalent Cu(1) and eight equivalent Zn(1) atoms to form AuZn8Cu4 cuboctahedra that share corners with two equivalent Au(1)Zn8Cu4 cuboctahedra, corners with eight equivalent Cu(1)Zn8Au4 cuboctahedra, edges with six equivalent Au(1)Zn8Cu4 cuboctahedra, faces with six equivalent Au(1)Zn8Cu4 cuboctahedra, and faces with six equivalent Cu(1)Zn8Au4 cuboctahedra. Cu(1) is bonded to four equivalent Au(1) and eight equivalent Zn(1) atoms to form CuZn8Au4 cuboctahedra that share corners with two equivalent Cu(1)Zn8Au4 cuboctahedra, corners with eight equivalent Au(1)Zn8Cu4 cuboctahedra, edges with six equivalent Cu(1)Zn8Au4 cuboctahedra, faces with six equivalent Au(1)Zn8Cu4 cuboctahedra, and faces with six equivalent Cu(1)Zn8Au4 cuboctahedra. Zn(1) is bonded in a 8-coordinate geometry to four equivalent Au(1) and four equivalent Cu(1) atoms.
