The compound described by MgAu3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Au(1) atoms to form a mixture of corner and face-sharing MgAu12 cuboctahedra. Au(1) is bonded in a distorted see-saw-like geometry to four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
