SmPr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Sm(1) is bonded to six equivalent Sm(1) and six equivalent Pr(1) atoms to form SmPr6Sm6 cuboctahedra that share corners with eighteen equivalent Sm(1)Pr6Sm6 cuboctahedra, edges with six equivalent Sm(1)Pr6Sm6 cuboctahedra, edges with twelve equivalent Pr(1)Pr6Sm6 cuboctahedra, faces with eight equivalent Sm(1)Pr6Sm6 cuboctahedra, and faces with twelve equivalent Pr(1)Pr6Sm6 cuboctahedra. Pr(1) is bonded to six equivalent Sm(1) and six equivalent Pr(1) atoms to form PrPr6Sm6 cuboctahedra that share corners with eighteen equivalent Pr(1)Pr6Sm6 cuboctahedra, edges with six equivalent Pr(1)Pr6Sm6 cuboctahedra, edges with twelve equivalent Sm(1)Pr6Sm6 cuboctahedra, faces with eight equivalent Pr(1)Pr6Sm6 cuboctahedra, and faces with twelve equivalent Sm(1)Pr6Sm6 cuboctahedra.
