Abstract: The asymmetric unit of the triclinic polymorph of the title compound, C21H25N3O3, consists of two mol­ecules, whereas for the monoclinic polymorph Z' = 1 [Fun et al. (2009). Acta Cryst. E65, o445]. The two mol­ecules exhibit an E configuration with respect to the C=N bond. The mol­ecules are linked into dimers by N-H...O and C-H...O hydrogen bonds forming R22(8) ring motifs. In addition, [pi]-[pi] inter­actions occur between nitro­phenyl groups [minimum centroid-centroid distance 3.940 (2) Å], stacking the molecules along the ac plane.
