The crystal structure described by Au9In4 is gamma-brass-like structured and crystallizes in the cubic P-43m space group. There are six inequivalent Au sites. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to two equivalent Au(2), two equivalent Au(3), one In(1), and four equivalent In(2) atoms. In the second Au site, Au(2) is bonded in a 13-coordinate geometry to one Au(2), two equivalent Au(4), four equivalent Au(1), two equivalent In(1), and four equivalent In(2) atoms. In the third Au site, Au(3) is bonded in a 13-coordinate geometry to one Au(3), two equivalent Au(5), two equivalent Au(6), four equivalent Au(1), and four equivalent In(2) atoms. In the fourth Au site, Au(4) is bonded in a 6-coordinate geometry to three equivalent Au(2), three equivalent In(1), and three equivalent In(2) atoms. In the fifth Au site, Au(5) is bonded in a 3-coordinate geometry to three equivalent Au(3) and three equivalent In(2) atoms. In the sixth Au site, Au(6) is bonded in a distorted trigonal planar geometry to three equivalent Au(3) and three equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to three equivalent Au(1), three equivalent Au(2), and three equivalent Au(4) atoms. In the second In site, In(2) is bonded in a 11-coordinate geometry to one Au(4), one Au(5), one Au(6), two equivalent Au(2), two equivalent Au(3), and four equivalent Au(1) atoms. is represented by the CIF card [CIF]
