CeAuAl crystallizes in the hexagonal P6_3/mmc space group. Ce(1) is bonded to six equivalent Au(1) and six equivalent Al(1) atoms to form a mixture of face and edge-sharing CeAl6Au6 cuboctahedra. Au(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Al(1) atoms. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Ce(1) and three equivalent Au(1) atoms.
