The material described by Au2Al crystallizes in the orthorhombic Pnma space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to five equivalent Al(1) atoms. In the second Au site, Au(2) is bonded in a 4-coordinate geometry to four equivalent Al(1) atoms. Al(1) is bonded in a distorted q6 geometry to four equivalent Au(2) and five equivalent Au(1) atoms. is represented by the CIF file [CIF]
