La5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second La site, La(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 La(1) and five equivalent La(2) atoms.
La5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All La(1)-Pb(1) bond lengths are 3.45 Å. In the second La site, La(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of La(2)-Pb(1) bond distances ranging from 3.29-3.85 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(1) and five equivalent La(2) atoms.
