TbSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Tb(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 Tb(1) atoms to form distorted STb5 trigonal bipyramids that share corners with twelve equivalent F(1)Tb4 tetrahedra, corners with four equivalent S(1)Tb5 trigonal bipyramids, edges with four equivalent F(1)Tb4 tetrahedra, and edges with eight equivalent S(1)Tb5 trigonal bipyramids. F(1) is bonded to four equivalent Tb(1) atoms to form FTb4 tetrahedra that share corners with four equivalent F(1)Tb4 tetrahedra, corners with twelve equivalent S(1)Tb5 trigonal bipyramids, edges with four equivalent F(1)Tb4 tetrahedra, and edges with four equivalent S(1)Tb5 trigonal bipyramids.
TbSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Tb(1) is bonded in a 9-coordinate geometry to five equivalent S(1) and four equivalent F(1) atoms. There are four shorter (2.81 Å) and one longer (2.86 Å) Tb(1)-S(1) bond length. All Tb(1)-F(1) bond lengths are 2.45 Å. S(1) is bonded to five equivalent Tb(1) atoms to form distorted STb5 trigonal bipyramids that share corners with twelve equivalent F(1)Tb4 tetrahedra, corners with four equivalent S(1)Tb5 trigonal bipyramids, edges with four equivalent F(1)Tb4 tetrahedra, and edges with eight equivalent S(1)Tb5 trigonal bipyramids.
