SrSmHfFeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sm(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Fe(1)O6 octahedra. Sm(1) is bonded to twelve equivalent O(1) atoms to form SmO12 cuboctahedra that share corners with twelve equivalent Sm(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Hf(1)O6 octahedra, and faces with four equivalent Fe(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Sm(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Sm(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Sr(1), two equivalent Sm(1), one Hf(1), and one Fe(1) atom.
