PrSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Pr(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 Pr(1) atoms to form distorted SPr5 trigonal bipyramids that share corners with twelve equivalent F(1)Pr4 tetrahedra, corners with four equivalent S(1)Pr5 trigonal bipyramids, edges with four equivalent F(1)Pr4 tetrahedra, and edges with eight equivalent S(1)Pr5 trigonal bipyramids. F(1) is bonded to four equivalent Pr(1) atoms to form FPr4 tetrahedra that share corners with four equivalent F(1)Pr4 tetrahedra, corners with twelve equivalent S(1)Pr5 trigonal bipyramids, edges with four equivalent F(1)Pr4 tetrahedra, and edges with four equivalent S(1)Pr5 trigonal bipyramids.
PrSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded in a 9-coordinate geometry to five equivalent S(1) and four equivalent F(1) atoms. There is one shorter (2.93 Å) and four longer (2.94 Å) Pr(1)-S(1) bond lengths. All Pr(1)-F(1) bond lengths are 2.55 Å. S(1) is bonded to five equivalent Pr(1) atoms to form distorted SPr5 trigonal bipyramids that share corners with twelve equivalent F(1)Pr4 tetrahedra, corners with four equivalent S(1)Pr5 trigonal bipyramids, edges with four equivalent F(1)Pr4 tetrahedra, and edges with eight equivalent S(1)Pr5 trigonal bipyramids. F(1) is bonded to four equivalent Pr(1) atoms to form FPr4 tetrahedra that share corners with four equivalent F(1)Pr4 tetrahedra, corners with twelve equivalent S(1)Pr5 trigonal bipyramids, edges with four equivalent F(1)Pr4 tetrahedra, and edges with four equivalent S(1)Pr5 trigonal bipyramids.
