La5Pb3S 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 S(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. S(1) is bonded to six equivalent La(1) atoms to form face-sharing SLa6 octahedra.
La5Pb3S 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 S(1) atoms. There are a spread of La(1)-Pb(1) bond distances ranging from 3.33-3.86 Å. Both La(1)-S(1) bond lengths are 2.96 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 3.46 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. S(1) is bonded to six equivalent La(1) atoms to form face-sharing SLa6 octahedra.
