In the title compound, C(21)H(18)N(4)O(4), there is an intra-molecular N-H⋯O hydrogen bond between the amino H atom and an O atom of the 2-nitro group of the adjacent benzene ring. The central benzene ring forms dihedral angles of 79.98 (7) and 82.88 (7)° with the two phenyl rings. In the crystal structure, mol-ecules are linked into a three-dimensional network by weak C-H⋯N, C-H⋯O and C-H⋯π inter-actions.
