The compound described by SmOF is Fluorite-derived structured and crystallizes in the trigonal R-3m 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 six equivalent O(1)Sm4 tetrahedra, corners with ten equivalent F(1)Sm4 tetrahedra, edges with three equivalent O(1)Sm4 tetrahedra, and edges with three equivalent F(1)Sm4 tetrahedra. F(1) is bonded to four equivalent Sm(1) atoms to form FSm4 tetrahedra that share corners with six equivalent F(1)Sm4 tetrahedra, corners with ten equivalent O(1)Sm4 tetrahedra, edges with three equivalent O(1)Sm4 tetrahedra, and edges with three equivalent F(1)Sm4 tetrahedra. is represented by the CIF file [CIF]
