The material structure described by LaSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. La(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 La(1) atoms to form distorted SLa5 trigonal bipyramids that share corners with twelve equivalent F(1)La4 tetrahedra, corners with four equivalent S(1)La5 trigonal bipyramids, edges with four equivalent F(1)La4 tetrahedra, and edges with eight equivalent S(1)La5 trigonal bipyramids. F(1) is bonded to four equivalent La(1) atoms to form FLa4 tetrahedra that share corners with four equivalent F(1)La4 tetrahedra, corners with twelve equivalent S(1)La5 trigonal bipyramids, edges with four equivalent F(1)La4 tetrahedra, and edges with four equivalent S(1)La5 trigonal bipyramids. is represented by the CIF card [CIF]
