CeAu is alpha-derived structured and crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to three equivalent Au(2) and four equivalent Au(1) atoms to form a mixture of distorted corner and edge-sharing CeAu7 hexagonal pyramids. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to three equivalent Au(1) and four equivalent Au(2) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 7-coordinate geometry to three equivalent Ce(2) and four equivalent Ce(1) atoms. In the second Au site, Au(2) is bonded in a 7-coordinate geometry to three equivalent Ce(1) and four equivalent Ce(2) atoms.

In the first Ce site, Ce(1) is bonded to three equivalent Au(2) and four equivalent Au(1) atoms to form a mixture of distorted corner and edge-sharing CeAu7 hexagonal pyramids. There are two shorter (3.15 Å) and one longer (3.18 Å) Ce(1)-Au(2) bond length. There are a spread of Ce(1)-Au(1) bond distances ranging from 3.13-3.17 Å. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to three equivalent Au(1) and four equivalent Au(2) atoms. There are two shorter (3.18 Å) and one longer (3.20 Å) Ce(2)-Au(1) bond length. There are a spread of Ce(2)-Au(2) bond distances ranging from 3.10-3.19 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 7-coordinate geometry to three equivalent Ce(2) and four equivalent Ce(1) atoms. In the second Au site, Au(2) is bonded in a 7-coordinate geometry to three equivalent Ce(1) and four equivalent Ce(2) atoms.
