The material structure described by CeSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 9-coordinate geometry to five equivalent S(1) and four equivalent F(1) atoms. S(1) is bonded to five equivalent Ce(1) atoms to form distorted SCe5 trigonal bipyramids that share corners with twelve equivalent F(1)Ce4 tetrahedra, corners with four equivalent S(1)Ce5 trigonal bipyramids, edges with four equivalent F(1)Ce4 tetrahedra, and edges with eight equivalent S(1)Ce5 trigonal bipyramids. F(1) is bonded to four equivalent Ce(1) atoms to form FCe4 tetrahedra that share corners with four equivalent F(1)Ce4 tetrahedra, corners with twelve equivalent S(1)Ce5 trigonal bipyramids, edges with four equivalent F(1)Ce4 tetrahedra, and edges with four equivalent S(1)Ce5 trigonal bipyramids. is represented by the CIF file [CIF]
