چکیده
The title compound, C(14)H(12)N(4)O(4), was prepared by the reaction of 2-nitro-phenyl isocyanate with benzoyl-hydrazine. The dihedral angle between the rings is 71.49 (6)) Å. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring. The crystal packing shows N-H⋯O hydrogen bonds.
