The material described by 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. is represented by the CIF file [CIF]
