The structure described by Lu2Au is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to four equivalent Au(1) atoms to form a mixture of edge and corner-sharing LuAu4 tetrahedra. In the second Lu site, Lu(2) is bonded in a 3-coordinate geometry to five equivalent Au(1) atoms. Au(1) is bonded in a 9-coordinate geometry to four equivalent Lu(1) and five equivalent Lu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
