(Z)-4-[(2-Amino-4,5-dichloroanilino)(phenyl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

Abstract: The molecule of the title compound, C₂₃H₁₈Cl₂N₄O, assumes a non-planar conformation in which the pyrazolone ring forms dihedral angles of 32.61 (19), 76.73 (14) and 52.57 (19)° with the three benzene rings. The secondary amino group is involved in an intramolecular N-HO hydrogen bond. In the crystal, molecules are linked by pairs of N-HO hydrogen bonds, forming inversion dimers. An offset stacking interaction is observed between the chloro-substituted benzene rings protruding on both sides of these dimers [centroid-centroid distance = 3.862 (1) Å].
