The material structure described by AuGa2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Au(1) is bonded in a 9-coordinate geometry to four equivalent Ga(1) and five 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 5-coordinate geometry to five equivalent Au(1) atoms. is represented by the CIF file [CIF]
