1-(4-Fluoro-phen-yl)-3-methyl-4-phenyl-sulfanyl-1H-pyrazol-5(4H)-one.

ABSTRACT: 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 ?-? [centroid-centroid distance = 3.6921?(7)?Å] and C-H?? inter-actions.
