Sr2Cu2ZnO2S2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. Zn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. S(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cu(1) atoms. O(1) is bonded to four equivalent Sr(1) and two equivalent Zn(1) atoms to form a mixture of edge, corner, and face-sharing OSr4Zn2 octahedra. The corner-sharing octahedra are not tilted.
