2,2-Diphenyl-N-{[2-(tri­fluoro­meth­yl)phen­yl]carbamo­thio­yl}acetamide

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—H...O 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—H...O and C—H...F hydrogen bonds link the mol­ecules into a layer parallel to the bc plane. A C—H...π inter­action is also observed.
