The material described by Ce2Au is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to four equivalent Au(1) atoms to form a mixture of corner and edge-sharing CeAu4 tetrahedra. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to five equivalent Au(1) atoms. Au(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms. is represented by the CIF file [CIF]
