AuGa2 crystallizes in the monoclinic P2_1/c space group. Au(1) is bonded in a 8-coordinate geometry to four equivalent Ga(1) and four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to four equivalent Au(1) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to four equivalent Au(1) atoms.
