Abstract

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