PuPt5 crystallizes in the hexagonal P6/mmm space group. Pu(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pt(2) and twelve equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Pu(1), four equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of face, corner, and edge-sharing PtPu4Pt8 cuboctahedra. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to three equivalent Pu(1), three equivalent Pt(2), and six equivalent Pt(1) atoms.
