PuAu3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Pu(1) is bonded in a distorted body-centered cubic geometry to six equivalent Au(2) and eight equivalent Au(1) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded to four equivalent Pu(1) and four equivalent Au(2) atoms to form a mixture of distorted edge, face, and corner-sharing AuPu4Au4 tetrahedra. In the second Au site, Au(2) is bonded in a 14-coordinate geometry to six equivalent Pu(1) and eight equivalent Au(1) atoms.
