Ce5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Ni(1) and five equivalent Pb(1) atoms to form a mixture of distorted edge, corner, and face-sharing CeNi2Pb5 pentagonal bipyramids. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Ni(1) is bonded to six equivalent Ce(1) atoms to form face-sharing NiCe6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(2) and five equivalent Ce(1) atoms.

In the first Ce site, Ce(1) is bonded to two equivalent Ni(1) and five equivalent Pb(1) atoms to form a mixture of distorted edge, corner, and face-sharing CeNi2Pb5 pentagonal bipyramids. Both Ce(1)-Ni(1) bond lengths are 2.80 Å. There are a spread of Ce(1)-Pb(1) bond distances ranging from 3.31-3.55 Å. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Ce(2)-Pb(1) bond lengths are 3.36 Å. Ni(1) is bonded to six equivalent Ce(1) atoms to form face-sharing NiCe6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(2) and five equivalent Ce(1) atoms.
