The material described by Au3Al is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded in a distorted see-saw-like geometry to four equivalent Al(1) atoms. Al(1) is bonded to twelve equivalent Au(1) atoms to form a mixture of face and corner-sharing AlAu12 cuboctahedra. is represented by the CIF card [CIF]
