PuGa6 crystallizes in the tetragonal P4/nbm space group. Pu(1) is bonded to four equivalent Ga(1) and eight equivalent Ga(2) atoms to form a mixture of face and edge-sharing PuGa12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to one Pu(1), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Pu(1), one Ga(2), and four equivalent Ga(1) atoms.
PuGa6 crystallizes in the tetragonal P4/nbm space group. Pu(1) is bonded to four equivalent Ga(1) and eight equivalent Ga(2) atoms to form a mixture of face and edge-sharing PuGa12 cuboctahedra. All Pu(1)-Ga(1) bond lengths are 3.10 Å. All Pu(1)-Ga(2) bond lengths are 3.18 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to one Pu(1), one Ga(1), and two equivalent Ga(2) atoms. The Ga(1)-Ga(1) bond length is 2.56 Å. Both Ga(1)-Ga(2) bond lengths are 2.62 Å. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Pu(1), one Ga(2), and four equivalent Ga(1) atoms. The Ga(2)-Ga(2) bond length is 2.41 Å.
