Crystals of the title compound, C 13 H 11 N 3 O 3 , were obtained from a condensation reaction of salicylaldehyde and 4-nitrophenylhydrazine. The molecule exhibits a planar structure, with the 4-nitro group slightly inclined to the plane. The molecules link to each other via intermolecular hydrogen
