2-{3-[1-(3,4-Dichlorophenyl)ethyl]-1,3-thiazolidin-2-ylidene}malononitrile

In the title compound, C14H11Cl2N3S, the thiazole ring is in an envelope conformation with the –CH2– group bonded to the S atom forming the flap. The crystal structure is stabilized by weak intermolecular C—H⋯Cl and C—H⋯N hydrogen bonds.
