The structure described by MgAu5 crystallizes in the trigonal R32 space group. Mg(1) is bonded to six equivalent Au(1) and six equivalent Au(2) atoms to form a mixture of corner and edge-sharing MgAu12 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Mg(1) atoms. In the second Au site, Au(2) is bonded in a distorted trigonal planar geometry to three equivalent Mg(1) atoms. is represented by the CIF file [CIF]
