X.-L. Zhen and J.-R. Han

Abstract: The molecule of the title compound, C₁₅H₁₅N₃O₄, is non-planar. The ethylvanillin group makes a dihedral angle of 7.68 (7)° with the nitrophenylhydrazine mean plane. A trifurcated intra/intermolecular O-H(O,O,O) hydrogen-bond system helps to establish the molecular conformation and consolidate the crystal packing.
