MgAu3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded to four equivalent Au(1) and eight equivalent Au(2) atoms to form a mixture of edge, face, and corner-sharing MgAu12 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted square co-planar geometry to four equivalent Mg(1) atoms. In the second Au site, Au(2) is bonded to four equivalent Mg(1) atoms to form a mixture of distorted edge and corner-sharing AuMg4 cuboctahedra.
