The crystal structure described by Au2Ga crystallizes in the orthorhombic Cmc2_1 space group. There are four inequivalent Au sites. In the first Au site, Au(1) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Ga(2) atoms. In the second Au site, Au(2) is bonded to one Ga(2) and three equivalent Ga(1) atoms to form distorted corner-sharing AuGa4 tetrahedra. In the third Au site, Au(3) is bonded in a 5-coordinate geometry to two equivalent Ga(2) and three equivalent Ga(1) atoms. In the fourth Au site, Au(4) is bonded in a 4-coordinate geometry to four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to two equivalent Au(1), three equivalent Au(2), and three equivalent Au(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to one Au(2), two equivalent Au(1), two equivalent Au(3), and four equivalent Au(4) atoms. is represented by the CIF card [CIF]
