CeCu5 crystallizes in the hexagonal P6/mmm space group. Ce(1) is bonded in a 18-coordinate geometry to six equivalent Cu(2) and twelve equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent Ce(1), four equivalent Cu(1), and four equivalent Cu(2) atoms to form a mixture of corner, face, and edge-sharing CuCe4Cu8 cuboctahedra. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Cu(1) atoms.
