La5Pb3Cl 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 7-coordinate geometry to five equivalent Pb(1) and two equivalent Cl(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. Cl(1) is bonded to six equivalent La(1) atoms to form face-sharing ClLa6 octahedra.
La5Pb3Cl 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 7-coordinate geometry to five equivalent Pb(1) and two equivalent Cl(1) atoms. There are a spread of La(1)-Pb(1) bond distances ranging from 3.32-3.72 Å. Both La(1)-Cl(1) bond lengths are 3.10 Å. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All La(2)-Pb(1) bond lengths are 3.49 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. Cl(1) is bonded to six equivalent La(1) atoms to form face-sharing ClLa6 octahedra.
