Gd5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second Gd site, Gd(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 Gd(1) and five equivalent Gd(2) atoms.
Gd5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Gd(1)-Pb(1) bond lengths are 3.29 Å. In the second Gd site, Gd(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of Gd(2)-Pb(1) bond distances ranging from 3.14-3.61 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1) and five equivalent Gd(2) atoms.
