The title compound, C(21)H(19)ClN(2)OS, exists in a cis conformation with respect to the N=C bond [1.2608 (13) Å]. The cyclo-hexene ring adopts a distorted half-chair conformation. The thia-zolidine 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, mol-ecules 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 inter-actions.
