Au4Zn crystallizes in the trigonal R-3m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Au(2) and three equivalent Zn(1) atoms. In the second Au site, Au(2) is bonded to three equivalent Au(1) and nine equivalent Au(2) atoms to form a mixture of face, corner, and edge-sharing AuAu12 cuboctahedra. Zn(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms.
Au4Zn crystallizes in the trigonal R-3m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Au(2) and three equivalent Zn(1) atoms. All Au(1)-Au(2) bond lengths are 2.98 Å. All Au(1)-Zn(1) bond lengths are 2.72 Å. In the second Au site, Au(2) is bonded to three equivalent Au(1) and nine equivalent Au(2) atoms to form a mixture of face, corner, and edge-sharing AuAu12 cuboctahedra. There are three shorter (2.95 Å) and six longer (2.98 Å) Au(2)-Au(2) bond lengths. Zn(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms.
