2-[2-(4-Acetyl­phen­yl)hydrazinyl­idene]-1,3-diphenyl­propane-1,3-dione

In the title compound, C(23)H(18)N(2)O(3), the inter­planar angle between the benzoyl units is 80.51 (6)° while the dihedral angles between the hydrazinyl­idene and benzoyl groups are 43.43 (6) and 54.16 (6)°. In the crystal, a strong resonance-assisted intra­molecular N—H⋯O hydrogen bond is observed. The mol­ecules form an inversion dimer via a pair of weak C—H⋯O hydrogen bonds and a π–π inter­action [centroid–centroid distance of 3.5719 (10) Å]. These dimers are linked via weak C—H⋯O contacts, forming chains along the b axis.
