Experimental Crystal data

R factor = 0.030; wR factor = 0.074; data-to-parameter ratio = 18.1. In the title compound, C17H12Cl2N2O2S2, the dithiacyclo-pentane ring has an envelope conformation with one of the methylene C atoms as the flap. The chlorophenyl rings make a dihedral angle of 82.63 (7). In the crystal, – interactions between the benzene rings of neighbouring molecules [centroid–centroid distance = 3.547 (2) Å] link the molecules into inversion dimers. Weak non-classical C—H X (X = O, N, Cl) interactions further consolidate the packing, forming a layer structure parallel to (110).
