( Z )-3-(4-Chlorophenyl)-2-(2-phenylcyclohex-2-en-1-ylimino)thiazolidin-4-one

The title compound, C21H19ClN2OS, exists in a cis conformation with respect to the N=C bond [1.2608 (13) Å]. The cyclohexene ring adopts a distorted half-chair conformation. The thiazolidine ring is close to being planar (r.m.s. deviation = 0.057 Å) and makes dihedral angles of 62.92 (6) and 56.32 (6)°, respectively, with the benzene ring and the chloro-substituted benzene ring. The dihedral angle between the benzene ring and the chloro-substituted benzene ring is 72.91 (6)°. In the crystal, molecules are linked by C—H...O and C—H...N hydrogen bonds into undulating sheets lying parallel to the bc plane. The crystal is further consolidated by C—H...π interactions.
