The structure described by PuSm3 crystallizes in the hexagonal P-6m2 space group. Pu(1) is bonded to six equivalent Pu(1) and six equivalent Sm(2) atoms to form PuSm6Pu6 cuboctahedra that share corners with six equivalent Pu(1)Sm6Pu6 cuboctahedra, corners with six equivalent Sm(1)Sm12 cuboctahedra, edges with six equivalent Pu(1)Sm6Pu6 cuboctahedra, edges with six equivalent Sm(1)Sm12 cuboctahedra, edges with twelve equivalent Sm(2)Sm9Pu3 cuboctahedra, faces with six equivalent Pu(1)Sm6Pu6 cuboctahedra, and faces with twelve equivalent Sm(2)Sm9Pu3 cuboctahedra. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded to six equivalent Sm(1) and six equivalent Sm(2) atoms to form SmSm12 cuboctahedra that share corners with six equivalent Pu(1)Sm6Pu6 cuboctahedra, corners with six equivalent Sm(1)Sm12 cuboctahedra, edges with six equivalent Pu(1)Sm6Pu6 cuboctahedra, edges with six equivalent Sm(1)Sm12 cuboctahedra, edges with twelve equivalent Sm(2)Sm9Pu3 cuboctahedra, faces with six equivalent Sm(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(2)Sm9Pu3 cuboctahedra. In the second Sm site, Sm(2) is bonded to three equivalent Pu(1), three equivalent Sm(1), and six equivalent Sm(2) atoms to form SmSm9Pu3 cuboctahedra that share corners with eighteen equivalent Sm(2)Sm9Pu3 cuboctahedra, edges with six equivalent Pu(1)Sm6Pu6 cuboctahedra, edges with six equivalent Sm(1)Sm12 cuboctahedra, edges with six equivalent Sm(2)Sm9Pu3 cuboctahedra, faces with six equivalent Pu(1)Sm6Pu6 cuboctahedra, faces with six equivalent Sm(1)Sm12 cuboctahedra, and faces with eight equivalent Sm(2)Sm9Pu3 cuboctahedra. is represented by the CIF card [CIF]
