4-Methyl-5-phenyl-1H-pyrazol-3(2H)-one
The asymmetric unit of the title compound, C(10)H(10)N(2)O, contains two crystallographically independent mol-ecules with similar geometries, which exist in the keto form. The C=O bond lengths are 1.2878 (12) Å in mol-ecule A and 1.2890 (12) Å in mol-ecule B, indicating that the compound undergoes enol-to-keto tautomerism during the crystallization process. In mol-ecule A, the pyrazole ring is ...

In the the title compound, C(27)H(23)ClN(4)O(2), the chloro-phenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O-H⋯O hydrogen bond generates an S(8) ring motif. The mol-ecules are linked int...
متن کامل4-[(5-Hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)phenylmethyl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol hemisolvate
The asymmetric unit of the title compound, C(27)H(24)N(4)O(2)·0.5C(2)H(6)O, comprises two crystallographically independent mol-ecules (A and B) with slightly different conformations, and one ethanol mol-ecule of crystallization. Intra-molecular C-H⋯O and O-H⋯O hydrogen bonds generate six- and eight-membered rings, producing S(6) and S(8) ring motifs, respectively. In mol-ecule A, one of the ben...
متن کاملCrystal structure of 4-[(2,4-dichlorophenyl)(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)methyl]-5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one
In the title compound C27H22Cl2N4O2, the pyrazol-5-ol ring makes a dihedral angle of 34.80 (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34 (12)° to its attached phenyl ring. In the crystal, N-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [010]. Inter-molecular π-π inter-actions are observed between the pyrazolone ring and the...
متن کامل4-[(3-Hydroxyanilino)(phenyl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C(23)H(19)N(3)O(2), the dihedral angles formed by the pyrazolone ring with the three benzene rings are 30.91 (6), 60.96 (4) and 57.01 (4)°. The ligand is in the enamine-keto form and its structure is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, O-H⋯N hydrogen bonds link mol-ecules into chains parallel to [01-1].
