The material described by Pu5Pb3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 6-coordinate geometry to two equivalent Pb(2) and four equivalent Pb(1) atoms. In the second Pu site, Pu(2) is bonded in a 6-coordinate geometry to two equivalent Pu(2) and four equivalent Pb(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted q6 geometry to two equivalent Pu(2) and eight equivalent Pu(1) atoms. In the second Pb site, Pb(2) is bonded in a 10-coordinate geometry to eight equivalent Pu(1) and two equivalent Pb(2) atoms. is represented by the CIF file [CIF]
