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.

A mixture of 3-(4-chlorophenyl)-5-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (0.333 g, 0.001 M) and phenacyl bromide (0.2 g, 0.001 M) in anhydrous ethanol (30 ml) was heated under reflux for about 4 h. The resultant solid was filtered and dried. Recrystallization was by slow evaporation of an ethanol solution of (I) to yield yellow cubes in 55% yield; M.pt: 418–419 K.
Carbon-bound H-atoms were placed in calculated positions (C—H = 0.93 to 0.98 Å) and were included in the

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound (I) was investigated owing to the established biological activities exhibited by related pyrazolin-1-carbothioamides (Abdel-Wahab et al. 2012; Lv et al., 2011; Chimenti et al., 2010; Abdel-Wahab et al. 2009). Herein, the crystal and molecular structure of (I) is described.
In (I), Fig. 1, the pyrazolyl ring is quite planar with a r.m.s. deviation of the five atoms being 0.030 Å. This is in contrast to the situation observed in the recently described derivative with a methyl rather than a chloride (Abdel-Wahab et al. 2013) whereby an envelope conformation was found for each of the two independent molecules; the methine-C atom was the flap atom in each case. In (I), the dihedral angle between the pyrazolyl and thiazole (r.m.s. deviation = 0.002 Å) rings is 2.83 (13)°. The thiazole-bound benzene ring is co-planar; dihedral angle = 4.34 (13)° with the thiazole. About the pyrazolyl ring, the chlorobenzene ring is co-planar, dihedral angle = 6.92 (14)°, but the benzene ring bound at C11 is perpendicular, dihedral angle = 85.77 (13)°. Thus, there are two planar, mutually perpendicular domains in the molecule which adopts a T-shape, as was the case for the aforementioned literature structure but which exhibited some twists, e.g. between the five-membered rings (Abdel-Wahab et al. 2013).
The most prominent feature of the crystal packing is the formation of dimeric aggregates between centrosymmetrically related molecules via π—π interactions between pyrazolyl rings [inter-centroid distance = 3.5370 (15) Å for symmetry operation: 1 - x, 1 - y, 1 - z], Fig. 2. Dimeric units stack along the a axis with no specific interactions between them, Fig. 3.
