Crystal structure of (2Z)-2-{(5Z)-5-[3-fluoro-2-(4-phenyl­piperidin-1-yl)benzyl­idene]-4-oxo-3-(p-tol­yl)-1,3-thia­zolidin-2-yl­idene}-N-(p-tol­yl)ethane­thio­amide dimethyl sulfoxide monosolvate

The title compound, C(37)H(34)FN(3)OS(2)·C(2)H(6)OS, was obtained by the Knoevenagel condensation. The thia­zolidine ring is essentially planar (r.m.s. deviation = 0.025 Å) and forms dihedral angles of 4.2 (3), 68.60 (14) and 39.57 (15)° with the attached thio­amide group, p-tolyl group benzene ring and fluoro-substituted benzene ring, respectively. The exocyclic double bonds are in a Z configuration. In the crystal, the dimethyl sulfoxide solvent mol­ecule is connected to the main mol­ecule via an N—H⋯O hydrogen bond. Weak C—H⋯O hydrogen bonds link the components of the structure into a two-dimensional network parallel to (10-1). Weak intra­molecular C—H⋯S hydrogen bonds are also observed. The crystal is an inversion twin with a ratio of twin components 0.78 (2):0.22 (6).
