PuAl3 is Uranium Silicide structured and crystallizes in the tetragonal P4/mmm space group. Pu(1) is bonded to four equivalent Al(1) and eight equivalent Al(2) atoms to form PuAl12 cuboctahedra that share corners with twelve equivalent Pu(1)Al12 cuboctahedra, edges with eight equivalent Al(1)Pu4Al8 cuboctahedra, edges with sixteen equivalent Al(2)Pu4Al8 cuboctahedra, faces with four equivalent Al(1)Pu4Al8 cuboctahedra, faces with six equivalent Pu(1)Al12 cuboctahedra, and faces with eight equivalent Al(2)Pu4Al8 cuboctahedra. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to four equivalent Pu(1) and eight equivalent Al(2) atoms to form distorted AlPu4Al8 cuboctahedra that share corners with twelve equivalent Al(1)Pu4Al8 cuboctahedra, edges with eight equivalent Pu(1)Al12 cuboctahedra, edges with sixteen equivalent Al(2)Pu4Al8 cuboctahedra, faces with four equivalent Pu(1)Al12 cuboctahedra, faces with six equivalent Al(1)Pu4Al8 cuboctahedra, and faces with eight equivalent Al(2)Pu4Al8 cuboctahedra. In the second Al site, Al(2) is bonded to four equivalent Pu(1), four equivalent Al(1), and four equivalent Al(2) atoms to form distorted AlPu4Al8 cuboctahedra that share corners with twelve equivalent Al(2)Pu4Al8 cuboctahedra, edges with eight equivalent Pu(1)Al12 cuboctahedra, edges with eight equivalent Al(1)Pu4Al8 cuboctahedra, edges with eight equivalent Al(2)Pu4Al8 cuboctahedra, faces with four equivalent Pu(1)Al12 cuboctahedra, faces with four equivalent Al(1)Pu4Al8 cuboctahedra, and faces with ten equivalent Al(2)Pu4Al8 cuboctahedra.
