Pu(GaAl)2 crystallizes in the orthorhombic Imma space group. Pu(1) is bonded in a 13-coordinate geometry to six equivalent Ga(1), three equivalent Al(1), and four equivalent Al(2) atoms. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Pu(1), three equivalent Ga(1), one Al(2), and three equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 13-coordinate geometry to three equivalent Pu(1), six equivalent Ga(1), and four equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 6-coordinate geometry to four equivalent Pu(1), two equivalent Ga(1), and four equivalent Al(1) atoms.
Pu(GaAl)2 crystallizes in the orthorhombic Imma space group. Pu(1) is bonded in a 13-coordinate geometry to six equivalent Ga(1), three equivalent Al(1), and four equivalent Al(2) atoms. There are four shorter (3.03 Å) and two longer (3.12 Å) Pu(1)-Ga(1) bond lengths. There is one shorter (3.05 Å) and two longer (3.15 Å) Pu(1)-Al(1) bond lengths. All Pu(1)-Al(2) bond lengths are 3.10 Å. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Pu(1), three equivalent Ga(1), one Al(2), and three equivalent Al(1) atoms.
