2-(4-Isobutyl-phen-yl)-N'-[1-(4-nitro-phen-yl)ethyl-idene]propanohydrazide.

ABSTRACT: The mol-ecule of the title compound, C(21)H(25)N(3)O(3), exists in a trans configuration with respect to the ethyl-idene unit. The dihedral angle between the two substituted benzene rings is 86.99 (7)°. The nitro group is twisted from the attached benzene ring at an angle of 17.02 (7)°. In the crystal structure, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds in a face-to-face manner into centrosymmetric dimers. These dimer units are further linked into chains along the c axis by weak C-H⋯O inter-actions. These chains are stacked along the b axis. The crystal is further stabilized by weak C-H⋯π inter-actions.
