The central pyrazole ring in the title compound, C17H16FN3S, adopts an envelope conformation with the methine C atom bearing the 4-fluoro-phenyl 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 fluoro-benzene ring is almost perpendicular [dihedral angle = 80.21 (11)°]. The thio-amide 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 intra-molecular hydrogen bond with a ring N atom. In the crystal, supra-molecular double layers in the bc plane are formed via N-H⋯S, N-H⋯F and C-H⋯F inter-actions.
