In the title compound, C16H14N4O5, the benzene ring of the nicotinate residue is inclined at an angle of 64.06 (10)° to the benzene ring of the nitro-phen-oxy group. The mol-ecules are linked by two inter-molecular C - H⋯O and N - H⋯N hydrogen bonds into a complex three-dimensional framework structure. C - H⋯π inter-actions also contribute to the stability of the crystal packing. ...
