CeCo5 crystallizes in the hexagonal P6/mmm space group. Ce(1) is bonded in a distorted hexagonal planar geometry to six equivalent Co(2) and twelve equivalent Co(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent Ce(1), four equivalent Co(1), and four equivalent Co(2) atoms to form a mixture of face, corner, and edge-sharing CoCe4Co8 cuboctahedra. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to three equivalent Ce(1), three equivalent Co(2), and six equivalent Co(1) atoms.
