SmOF is half-Heusler structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. O(1) is bonded to four equivalent Sm(1) atoms to form OSm4 tetrahedra that share corners with four equivalent F(1)Sm4 tetrahedra, corners with twelve equivalent O(1)Sm4 tetrahedra, and edges with six equivalent F(1)Sm4 tetrahedra. F(1) is bonded to four equivalent Sm(1) atoms to form FSm4 tetrahedra that share corners with four equivalent O(1)Sm4 tetrahedra, corners with twelve equivalent F(1)Sm4 tetrahedra, and edges with six equivalent O(1)Sm4 tetrahedra.
