In the title compound, C24H17ClFN3S, the pyrazole ring is almost planar (r.m.s. deviation = 0.030 Å). With the exception of the methine-bound benzene ring, which forms a dihedral angle of 85.77 (13)° with the pyrazole ring, the remaining non-C atoms lie in an approximate plane (r.m.s. deviation = 0.084 Å) so that overall the mol­ecule has a T-shape. In the crystal, centrosymmetrically related mol­ecules are connected via π–π inter­actions between pyrazole rings [centroid–centroid distance = 3.5370 (15) Å] and these stack along the a axis with no specific inter­actions between them.

In the title compound, C18H14N6O2, the benzene ring is slightly twisted out of the plane of the 1,2,3-triazole ring (r.m.s. deviation = 0.010 Å), forming a dihedral angle of 6.20 (13)°. The nine non-H ring atoms of the fused five- and six-membered ring system are almost coplanar (r.m.s. deviation = 0.032 Å). The near coplanarity in the central residue is consolidated by an intra­molecular bifurcated N—H...(O,N) hydrogen bond. The conformation about the N=C bond is Z. In the crystal, supra­molecular chains along [101] are sustained by N—H...O hydrogen bonds and C—H...O inter­actions. These are consolidated into a three-dimensional architecture by C—H...π and π–π inter­actions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid–centroid distance = 3.6056 (14) Å].

In the title compound, C28H23FN6S, the pyrazole ring adopts an envelope conformation, with the methine C atom being the flap atom. With respect to this ring, the 2-thienyl, triazole and fluoro­benzene rings are approximately coplanar, coplanar and perpendicular, respectively [dihedral angles = 8.56 (17), 6.03 (19) and 73.1 (2)°, respectively] so that to a first approximation the mol­ecule has a T-shape. In the crystal, mol­ecules are consolidated into a three-dimensional architecture by C—H...F (involving a bifurcated F atom), C—H...S and C—H...π inter­actions.

In the title compound, C26H23FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The thio­urea group is close to being coplanar with the pyrazole N atoms [N—N—C—S torsion angle = 176.78 (15)°], which allows for an intra­molecular N—H...N hydrogen bond; the connected triazole ring is nearly coplanar with this ring [N—C—C—N = −172.65 (19)°]. There is a significant twist between the pyrazole ring and attached fluoro­benzene ring [N—C—C—C = −18.8 (3)°] and a greater twist between triazole and attached tolyl ring [dihedral angle = 58.25 (14)°]. In the crystal, supra­molecular chains aligned along [40,10] are consolidated by π–π inter­actions between the triazole and phenyl rings [centroid–centroid distance = 3.7053 (13) Å].
