2-[2-(4-Acetyl-phen-yl)hydrazinyl-idene]-1,3-diphenyl-propane-1,3-dione.


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 ?-? 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.

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,  ...[more]
