Au4Mn crystallizes in the trigonal R-3m space group. Mn(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Mn(1) and three equivalent Au(2) 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 corner, face, and edge-sharing AuAu12 cuboctahedra.
Au4Mn crystallizes in the trigonal R-3m space group. Mn(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. All Mn(1)-Au(1) bond lengths are 2.72 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Mn(1) and three equivalent Au(2) atoms. All Au(1)-Au(2) bond lengths are 2.96 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 corner, face, and edge-sharing AuAu12 cuboctahedra. There are three shorter (2.96 Å) and six longer (3.00 Å) Au(2)-Au(2) bond lengths.
