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 five equivalent In(1) atoms. In the second Au site, Au(2) is bonded in a 6-coordinate geometry to six equivalent In(1) atoms. In(1) is bonded in a distorted body-centered cubic 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. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to five equivalent In(1) atoms. There are a spread of Au(1)-In(1) bond distances ranging from 2.80-3.19 Å. In the second Au site, Au(2) is bonded in a 6-coordinate geometry to six equivalent In(1) atoms. All Au(2)-In(1) bond lengths are 2.88 Å. In(1) is bonded in a distorted body-centered cubic geometry to three equivalent Au(2) and five equivalent Au(1) atoms.
