SmLa7Mn8O24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded to twelve equivalent O(2) atoms to form SmO12 cuboctahedra that share corners with twelve equivalent La(2)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, and faces with eight equivalent Mn(1)O6 octahedra.
