چکیده
The title compound, C(15)H(15)N(3)O(4), a Schiff base, was obtained from a condensation reaction of 3-eth-oxy-4-hydroxy-benzaldehyde and 2-nitro-phenyl-hydrazine. The mol-ecule is approximately planar, the largest deviation from the mean plane being 0.1449 (16) Å. An intramolecular N-H⋯O inter-action is also present. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules, forming chain parallel to the b axis.
