Materials Data on Fe3(SnS4)2 by Materials Project
Fe3(SnS4)2 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six S2- atoms to form FeS6 octahedra that share corners with three equivalent FeS4 tetrahedra, edges with two equivalent FeS6 octahedra, and edges with four equivalent SnS6 octahedra. There are a spread of Fe–S bond distances ranging from 2.25–2.44 Å. In the second Fe+2.67+ site, Fe+2.67+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with six equivalent FeS6 octahedra and corners with six equivalent SnS6 octahedra. The corner-sharing octahedra tilt angles range from 49–67°. There are two shorter (2.27 Å) and two longer (2.37 Å) Fe–S bond lengths. Sn4+ is bonded to six S2- atoms to form SnS6 octahedra that share corners with three equivalent FeS4 tetrahedra, edges with two equivalent SnS6 octahedra, and edges with four equivalent FeS6 octahedra. There are a spread of Sn–S bond distances ranging from 2.55–2.64 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to two Fe+2.67+ and two equivalent Sn4+ atoms. In the second S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three Fe+2.67+ and one Sn4+ atom. In the third S2- site, S2- is bonded in a 3-coordinate geometry to two equivalent Fe+2.67+ and one Sn4+ atom. In the fourth S2- site, S2- is bonded in a 3-coordinate geometry to one Fe+2.67+ and two equivalent Sn4+ atoms.
