The compound described by Fe3(SnS4)2 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one S(1), one S(4), two equivalent S(2), and two equivalent S(3) atoms to form FeS6 octahedra that share corners with three equivalent Fe(2)S4 tetrahedra, edges with two equivalent Fe(1)S6 octahedra, and edges with four equivalent Sn(1)S6 octahedra. In the second Fe site, Fe(2) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form FeS4 tetrahedra that share corners with six equivalent Fe(1)S6 octahedra and corners with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 49-67°. Sn(1) is bonded to one S(2), one S(3), two equivalent S(1), and two equivalent S(4) atoms to form SnS6 octahedra that share corners with three equivalent Fe(2)S4 tetrahedra, edges with two equivalent Sn(1)S6 octahedra, and edges with four equivalent Fe(1)S6 octahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Fe(1), one Fe(2), and two equivalent Sn(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to one Fe(2), two equivalent Fe(1), and one Sn(1) atom. In the third S site, S(3) is bonded in a distorted T-shaped geometry to two equivalent Fe(1) and one Sn(1) atom. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to one Fe(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
