CrCuSnS4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Cr(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CrS6 octahedra that share corners with six equivalent Cu(1)S4 tetrahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent Sn(1)S6 octahedra. Cu(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form CuS4 tetrahedra that share corners with six equivalent Cr(1)S6 octahedra and corners with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 50-62°. Sn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form SnS6 octahedra that share corners with six equivalent Cu(1)S4 tetrahedra, edges with two equivalent Sn(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Cr(1), one Cu(1), and two equivalent Sn(1) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Cr(1), one Cu(1), and one Sn(1) atom.
