In the title compound, C17H12Cl2N2O2S2, the di-thia-cyclo-pentane ring has an envelope conformation with one of the methyl-ene C atoms as the flap. The chloro-phenyl rings make a dihedral angle of 82.63 (7)°. In the crystal, π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.547 (2) Å] link the mol-ecules into inversion dimers. Weak non-classical C-H⋯X (X = O, N, Cl) inter-actions further consolidate the packing, forming a layer structure parallel to (110).
