In the title compound, C(20)H(19)FN(6)S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angle between the least-squares plane through the pyrazole and triazole rings is 7.59 (9)°, and the triazole and attached benzene ring form a dihedral angle of 74.79 (9)°. The thio-urea group is coplanar with the pyrazole ring [N-N-C-S torsion angle = -179.93 (11)°], which enables the formation of an intra-molecular N-H⋯N hydrogen bond. In the crystal, inversion-related mol-ecules associate via N-H⋯S hydrogen bonds and eight-membered {⋯HNCS}(2) synthons feature in the crystal packing. These synthons are connected into supra-molecular chains along the a axis via N-H⋯F hydrogen bonds, and the chains are consolidated into layers in the ab plane via C-H⋯S and C-H⋯F contacts.
