Abstract
The molecule of the title compound, C21H25N3O3, exists in a trans configuration with respect to the ethylidene 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, molecules 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 interactions. These chains are stacked along the b axis. The crystal is further stabilized by weak C—H⋯π interactions.
