The title compound, C 16 H 16 N 2 O 4 , was synthesized by the reaction of 3-hydroxy-4-methoxybenzaldehyde with hydrazine hydrate. The molecule possesses a crystallographically imposed centre of symmetry. An intramolecular O-HÁ Á ÁO hydrogen bond promotes planarity of the molecular backbone. In the
