Ce5AgPb3 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 to two equivalent Ag(1) and five equivalent Pb(1) atoms to form a mixture of distorted corner, edge, and face-sharing CeAg2Pb5 pentagonal bipyramids. Ag(1) is bonded to six equivalent Ce(2) atoms to form distorted face-sharing AgCe6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
Ce5AgPb3 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. All Ce(1)-Pb(1) bond lengths are 3.50 Å. In the second Ce site, Ce(2) is bonded to two equivalent Ag(1) and five equivalent Pb(1) atoms to form a mixture of distorted corner, edge, and face-sharing CeAg2Pb5 pentagonal bipyramids. Both Ce(2)-Ag(1) bond lengths are 3.20 Å. There are a spread of Ce(2)-Pb(1) bond distances ranging from 3.27-3.45 Å. Ag(1) is bonded to six equivalent Ce(2) atoms to form distorted face-sharing AgCe6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
