摘要：
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)degrees with the three benzene rings. The secondary amino group is involved in an intramolecular N-H center dot center dot center dot O hydrogen bond. In the crystal, molecules are linked by pairs of N-H center dot center dot center dot O 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) angstrom].
