In the title compound, C20H19FN6S, 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 thiourea group is coplanar with the pyrazole ring [N—N—C—S torsion angle = −179.93 (11)°], which enables the formation of an intramolecular N—HN hydrogen bond. In the crystal, inversion-related molecules associate via N—HS hydrogen bonds and eight-membered {HNCS}2 synthons feature in the crystal packing. These synthons are connected into supramolecular chains along the a axis via N—HF hydrogen bonds, and the chains are consolidated into layers in the ab plane via C—HS and C—HF contacts.
