Crystal structure of (2Z)-2-{(5Z)-5-[3-fluoro-2-(4-phenyl-piperidin-1-yl)benzyl-idene]-4-oxo-3-(p-tol-yl)-1,3-thia-zolidin-2-yl-idene}-N-(p-tol-yl)ethane-thio-amide dimethyl sulfoxide monosolvate.

Abstract

The title compound, C37H34FN3OS2·C2H6OS, 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).
