Ca2SnS4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ca(1) is bonded to six equivalent S(1) atoms to form CaS6 octahedra that share corners with six equivalent Sn(1)S4 tetrahedra and edges with six equivalent Ca(1)S6 octahedra. Sn(1) is bonded to four equivalent S(1) atoms to form SnS4 tetrahedra that share corners with twelve equivalent Ca(1)S6 octahedra. The corner-sharing octahedral tilt angles are 55°. S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Ca(1) and one Sn(1) atom.
