4‐[(2‐Hydro­xy­phenyl­amino)­phenyl­methyl­ene]‐5‐methyl‐2‐phenyl‐2H‐pyrazol‐3(4H)‐one

The title compound, C23H19N3O2, a condensation product of 1‐phenyl‐3‐methyl‐4‐benzoyl‐5‐pyrazolone and o‐amino­phenol, is a neutral tridentate ligand in en­amine–keto form, due to a strong intramolecular N—H⋯O hydrogen bond. A pair of intermolecular O—H⋯O hydrogen bonds link mol­ecules to give dimer...

Zusammenfassung:The title compound, C23H19N3O2, a condensation product of 1‐phenyl‐3‐methyl‐4‐benzoyl‐5‐pyrazolone and o‐amino­phenol, is a neutral tridentate ligand in en­amine–keto form, due to a strong intramolecular N—H⋯O hydrogen bond. A pair of intermolecular O—H⋯O hydrogen bonds link mol­ecules to give dimers.
