PuPt3 crystallizes in the tetragonal I-4 space group. Pu(1) is bonded in a 12-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), and four equivalent Pt(3) atoms. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted L-shaped geometry to four equivalent Pu(1) and one Pt(2) atom. In the second Pt site, Pt(2) is bonded in a 10-coordinate geometry to four equivalent Pu(1), one Pt(1), two equivalent Pt(3), and three equivalent Pt(2) atoms. In the third Pt site, Pt(3) is bonded in a 3-coordinate geometry to four equivalent Pu(1) and two equivalent Pt(2) atoms.
PuPt3 crystallizes in the tetragonal I-4 space group. Pu(1) is bonded in a 12-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), and four equivalent Pt(3) atoms. There are a spread of Pu(1)-Pt(1) bond distances ranging from 2.64-3.46 Å. There are a spread of Pu(1)-Pt(2) bond distances ranging from 2.69-3.30 Å. There are a spread of Pu(1)-Pt(3) bond distances ranging from 2.88-3.41 Å. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted L-shaped geometry to four equivalent Pu(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 2.69 Å. In the second Pt site, Pt(2) is bonded in a 10-coordinate geometry to four equivalent Pu(1), one Pt(1), two equivalent Pt(3), and three equivalent Pt(2) atoms.
