In the two mol-ecules of the asymmetric unit of the title compound, C(12)H(11)N(3)O(4), the seven-membered diazepine ring adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methine C atom the prow). The five-membered pyrrole ring, which has an envelope conformation, makes dihedral angles of 60.47 (10) and 54.69 (9)° with the benzene ring of the benzodiazepine unit in the two mol-ecules. In the crystal, inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.8023 (7)-3.8946 (7) Å] lead to the formation of a three-dimensional framework.
