The crystal structure described by Au4Al crystallizes in the monoclinic C2/m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Au(2) and three equivalent Al(1) atoms. In the second Au site, Au(2) is bonded in a distorted q6 geometry to three equivalent Au(1) and seven equivalent Au(2) atoms. Al(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. is represented by the CIF card [CIF]
