چکیده
In the title compound, C(14)H(18)N(2)O(3)S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005 (1) Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09 (5)°. Pairs of inter-molecular N-H⋯O and O⋯H⋯N hydrogen bonds form dimers between neighboring mol-ecules, generating R(2) (2)(10) ring motifs. These dimers are further linked by intermolecular N-H⋯O and O-H⋯N hydrogen bonds into two-dimensional arrays parallel to the ac plane. The crystal structure is also stabilized by C-H⋯π inter-actions.

متن کاملOn the Tautomerism of N-Substituted Pyrazolones: 1,2-Dihydro-3H-pyrazol-3-ones versus 1H-Pyrazol-3-ols.
The tautomerism of 1-phenyl-1,2-dihydro-3H-pyrazol-3-One was investigated. An X-ray crystal structure analysis exhibits dimers of 1-phenyl-1H-pyrazol-3-ol units. Comparison of NMR (nuclear magnetic resonance) spectra in liquid state (¹H, 13C, 15N) with those of "fixed" derivatives, as well as with the corresponding solid state NMR spectra reveal this compound to exist predominantly as 1H-pyrazo...
