Abstract

In the title compound, C26H23FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The thio-urea group is close to being coplanar with the pyrazole N atoms [N-N-C-S torsion angle = 176.78 (15)°], which allows for an intra-molecular 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 fluoro-benzene 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, supra-molecular chains aligned along [40,10] are consolidated by π-π inter-actions between the triazole and phenyl rings [centroid-centroid distance = 3.7053 (13) Å].
