چکیده
The title compound, C(16)H(13)FN(2)OS, has undergone enol-to-keto tautomerism during the crystallization process. The 1H-pyrazole-5-one ring [maximum deviation = 0.0198 (11) Å] is inclined at angles of 33.10 (5) and 79.57 (5)° with respect to the fluoro-phenyl [maximum deviation = 0.0090 (12) Å] and phenyl-thiol [maximum deviation = 0.0229 (3) Å] rings attached to it. In the crystal, neighbouring mol-ecules are linked into inversion dimers, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane via inter-molecular N-H⋯O, C-H⋯F and C-H⋯O hydrogen bonds. The crystal is further stabilized by weak π-π [centroid-centroid distance = 3.6921 (7) Å] and C-H⋯π inter-actions.

The title compound, C(23)H(18)ClN(3)O, was synthesized by the reaction of 4-chloro-aniline and 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one. The terminal benzene rings are twisted at dihedral angles of 48.3 (2), 71.4 (2) and 36.1 (2)° with respect to the central eight-atom methyl-pyrazolone/amino-methyl-ene unit. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation [mea...
