The material described by PuPb2 crystallizes in the tetragonal I4_1/amd space group. Pu(1) is bonded in a 10-coordinate geometry to four equivalent Pb(1) and six equivalent Pb(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Pu(1) atoms. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to six equivalent Pu(1) atoms. is represented by the CIF file [CIF]
