Abstract: 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 [pi]-[pi] interactions between pyrazole rings [centroid-centroid distance = 3.5370 (15) Å] and these stack along the a axis with no specific interactions between them.
