Au3In2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to three equivalent Au(2) and five equivalent In(1) atoms. In the second Au site, Au(2) is bonded to six equivalent Au(1) and six equivalent In(1) atoms to form face-sharing AuIn6Au6 cuboctahedra. In(1) is bonded in a 5-coordinate geometry to three equivalent Au(2) and five equivalent Au(1) atoms.
Au3In2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Au sites.
