Pr5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second Pr site, Pr(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 Pr(1) and five equivalent Pr(2) atoms.
Pr5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Pr(1)-Pb(1) bond lengths are 3.39 Å. In the second Pr site, Pr(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of Pr(2)-Pb(1) bond distances ranging from 3.24-3.78 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1) and five equivalent Pr(2) atoms.
