The material structure described by Au2Mg crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 9-coordinate geometry to four equivalent Au(1) and five equivalent Au(2) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. In the second Au site, Au(2) is bonded in a 5-coordinate geometry to five equivalent Mg(1) atoms. is represented by the CIF file [CIF]
