PaSm is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Pa(1) is bonded to six equivalent Pa(1) and six equivalent Sm(1) atoms to form PaSm6Pa6 cuboctahedra that share corners with eighteen equivalent Pa(1)Sm6Pa6 cuboctahedra, edges with six equivalent Pa(1)Sm6Pa6 cuboctahedra, edges with twelve equivalent Sm(1)Sm6Pa6 cuboctahedra, faces with eight equivalent Pa(1)Sm6Pa6 cuboctahedra, and faces with twelve equivalent Sm(1)Sm6Pa6 cuboctahedra. Sm(1) is bonded to six equivalent Pa(1) and six equivalent Sm(1) atoms to form SmSm6Pa6 cuboctahedra that share corners with eighteen equivalent Sm(1)Sm6Pa6 cuboctahedra, edges with six equivalent Sm(1)Sm6Pa6 cuboctahedra, edges with twelve equivalent Pa(1)Sm6Pa6 cuboctahedra, faces with eight equivalent Sm(1)Sm6Pa6 cuboctahedra, and faces with twelve equivalent Pa(1)Sm6Pa6 cuboctahedra.
