In the mol-ecule of the title compound, C(14)H(12)N(2)O(4), the aromatic rings are oriented at a dihedral angle of 51.50 (4)°. An intra-molecular N-H⋯O inter-action results in the formation of a six-membered ring having an envelope conformation. In the crystal structure, inter-molecular N-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers. π-π contacts between the benzene rings [centroid-centroid distance = 3.708 (1) Å] may further stabilize the structure. ...[more]
