Materials Data on PuPb2 by Materials Project
PuPb2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Pu is bonded in a 10-coordinate geometry to ten Pb atoms. There are a spread of Pu–Pb bond distances ranging from 3.37–3.48 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a distorted rectangular see-saw-like geometry to four equivalent Pu atoms. In the second Pb site, Pb is bonded in a 12-coordinate geometry to six equivalent Pu atoms.
