The asymmetric unit of the triclinic polymorph of the title compound, C21H25N3O3, consists of two molecules, whereas for the monoclinic polymorph Z0 = 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—HO and C—HO hydrogen bonds forming R2 2 (8) ring motifs. In addition, – interactions occur between nitrophenyl groups [minimum centroid–centroid distance 3.940 (2) A˚ ], stacking the molecules along the ac plane.
