Abstract
The central pyrazole ring in the title compound, C17H16FN3S, adopts an envelope conformation with the methine C atom bearing the 4-fluorophenyl substituent as the flap atom. Whereas the tolyl ring is slightly twisted out of the least-squares plane through the pyrazole ring [dihedral angle = 13.51 (11)°], the fluorobenzene ring is almost perpendicular [dihedral angle = 80.21 (11)°]. The thioamide group is almost coplanar with the N—N bond of the ring [N—N—C—N torsion angle = 1.2 (3)°] and the amine group forms an intramolecular hydrogen bond with a ring N atom. In the crystal, supramolecular double layers in the bc plane are formed via N—H⋯S, N—H⋯F and C—H⋯F interactions.
