Cu(SnS2)4 is beta indium sulfide-derived structured and crystallizes in the cubic F-43m space group. Cu(1) is bonded to four equivalent S(1) atoms to form CuS4 tetrahedra that share corners with twelve equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles are 57°. Sn(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form SnS6 octahedra that share corners with three equivalent Cu(1)S4 tetrahedra and edges with six equivalent Sn(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to one Cu(1) and three equivalent Sn(1) atoms. In the second S site, S(2) is bonded in a distorted T-shaped geometry to three equivalent Sn(1) atoms.
