Abstract: The title molecule, C22H17F3N2OS, adopts a trans-cis conformation with respect to the positions of the carbonyl and trifluoromethylbenzene groups against the thiocarbonyl group across the C-N bonds. The molecular structure is stabilized by an intramolecular N-HO hydrogen bond with an S(6) ring motif. The trifluoromethyl-substituted benzene ring forms dihedral angles of 66.05 (9) and 47.19 (9)° with the terminal phenyl rings and is twisted from the O=C-N-(C=S)-N carbonylthiourea plane [maximum deviation = 0.0535 (12) Å], making a dihedral angle of 63.59 (8)°. In the crystal, N-HO and C-HF hydrogen bonds link the molecules into a layer parallel to the bc plane. A C-H interaction is also observed.
