Sr2SnS3F2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 4-coordinate geometry to one S(2), four equivalent S(1), and four equivalent F(1) atoms. Sn(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form corner-sharing SnS4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one Sn(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Sr(1) and two equivalent Sn(1) atoms. F(1) is bonded to four equivalent Sr(1) atoms to form a mixture of corner and edge-sharing FSr4 tetrahedra.
Sr2SnS3F2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 4-coordinate geometry to one S(2), four equivalent S(1), and four equivalent F(1) atoms. The Sr(1)-S(2) bond length is 3.37 Å. There are a spread of Sr(1)-S(1) bond distances ranging from 3.16-3.29 Å. There are three shorter (2.55 Å) and one longer (2.56 Å) Sr(1)-F(1) bond length. Sn(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form corner-sharing SnS4 tetrahedra. Both Sn(1)-S(1) bond lengths are 2.37 Å. There is one shorter (2.47 Å) and one longer (2.49 Å) Sn(1)-S(2) bond length. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one Sn(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Sr(1) and two equivalent Sn(1) atoms.
