The material structure described by Fe3Cd(SnS4)2 is Spinel-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 two equivalent S(1) and two equivalent S(2) atoms to form FeS4 tetrahedra that share corners with six equivalent Fe(2)S6 octahedra and corners with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 47-66°. In the second Fe site, Fe(2) is bonded to one S(1), one S(3), two equivalent S(2), and two equivalent S(4) atoms to form FeS6 octahedra that share corners with three equivalent Fe(1)S4 tetrahedra, corners with three equivalent Cd(1)S4 tetrahedra, edges with two equivalent Fe(2)S6 octahedra, and edges with four equivalent Sn(1)S6 octahedra. Cd(1) is bonded to two equivalent S(3) and two equivalent S(4) atoms to form CdS4 tetrahedra that share corners with six equivalent Fe(2)S6 octahedra and corners with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 43-74°. Sn(1) is bonded to one S(2), one S(4), two equivalent S(1), and two equivalent S(3) atoms to form SnS6 octahedra that share corners with three equivalent Fe(1)S4 tetrahedra, corners with three equivalent Cd(1)S4 tetrahedra, edges with two equivalent Sn(1)S6 octahedra, and edges with four equivalent Fe(2)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 rectangular see-saw-like geometry to one Fe(1), two equivalent Fe(2), and one Sn(1) atom. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to one Fe(2), one Cd(1), and two equivalent Sn(1) atoms. In the fourth S site, S(4) is bonded to two equivalent Fe(2), one Cd(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing SCdFe2Sn trigonal pyramids. is represented by the CIF card [CIF]
