The title compound, C(15)H(13)N(3)O(4), was synthesized by the reaction of equimolar quantities of 2-methoxybenzaldehyde and 2-nitrobenzohydrazide in methanol. The dihedral angle between the two substituted benzene rings is 68.3 (2)degrees. In the crystal structure, inversion dimers linked by pairs of N-H center dot cente...
