The compound described by Au7Ga2 crystallizes in the hexagonal P-62m space group. There are six inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted trigonal non-coplanar geometry to one Au(4), one Ga(2), and two equivalent Ga(1) atoms. In the second Au site, Au(2) is bonded in a distorted trigonal planar geometry to three equivalent Au(4), one Ga(2), and two equivalent Ga(1) atoms. In the third Au site, Au(3) is bonded in a 2-coordinate geometry to two equivalent Ga(2) atoms. In the fourth Au site, Au(4) is bonded in a 13-coordinate geometry to one Au(6), two equivalent Au(1), six equivalent Au(2), and four equivalent Ga(1) atoms. In the fifth Au site, Au(5) is bonded in a distorted linear geometry to two equivalent Ga(1) atoms. In the sixth Au site, Au(6) is bonded in a distorted linear geometry to three equivalent Au(4) and two equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Au(5), three equivalent Au(1), three equivalent Au(2), and three equivalent Au(4) atoms. In the second Ga site, Ga(2) is bonded in a distorted q6 geometry to one Au(6), three equivalent Au(1), three equivalent Au(2), and three equivalent Au(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
