Materials Data on Pu3Au by Materials Project
Pu3Au is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Pu sites. In the first Pu site, Pu is bonded to four equivalent Pu and four equivalent Au atoms to form a mixture of distorted corner, edge, and face-sharing PuPu4Au4 tetrahedra. All Pu–Pu bond lengths are 2.92 Å. All Pu–Au bond lengths are 2.92 Å. In the second Pu site, Pu is bonded in a 8-coordinate geometry to eight equivalent Pu and six equivalent Au atoms. All Pu–Au bond lengths are 3.37 Å. Au is bonded in a distorted body-centered cubic geometry to fourteen Pu atoms.
