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.

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. There are a spread of Ce(1)-Au(1) bond distances ranging from 3.01-3.09 Å. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to five equivalent Au(1) atoms. There are a spread of Ce(2)-Au(1) bond distances ranging from 3.19-3.61 Å. Au(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
