La3Au is Uranium Silicide structured and crystallizes in the trigonal R3m space group. La(1) is bonded in a 3-coordinate geometry to four equivalent Au(1) atoms. There are a spread of La(1)-Au(1) bond distances ranging from 3.09-3.83 Å. Au(1) is bonded to twelve equivalent La(1) atoms to form a mixture of distorted face and corner-sharing AuLa12 cuboctahedra.
