Ba2SnS3F2 crystallizes in the orthorhombic Pnma space group. Ba(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 Ba(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 Ba(1) and two equivalent Sn(1) atoms. F(1) is bonded to four equivalent Ba(1) atoms to form a mixture of edge and corner-sharing FBa4 tetrahedra.
Ba2SnS3F2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 4-coordinate geometry to one S(2), four equivalent S(1), and four equivalent F(1) atoms. The Ba(1)-S(2) bond length is 3.38 Å. There are a spread of Ba(1)-S(1) bond distances ranging from 3.33-3.47 Å. There are two shorter (2.68 Å) and two longer (2.69 Å) Ba(1)-F(1) bond lengths. 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 2.35 Å. There is one shorter (2.47 Å) and one longer (2.48 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 Ba(1) and one Sn(1) atom.
