CePd5 crystallizes in the hexagonal P6/mmm space group. Ce(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(2) and twelve equivalent Pd(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Ce(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form a mixture of edge, corner, and face-sharing PdCe4Pd8 cuboctahedra. In the second Pd site, Pd(2) is bonded in a 3-coordinate geometry to three equivalent Ce(1) and six equivalent Pd(1) atoms.
