The structure described by Ce5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms. is represented by the CIF card [CIF]
