In the title mol-ecule, C22H22N2O4, the eth-oxy-phenyl rings are oriented at dihedral angles of 69.31 (13) and 75.90 (13)° to the nitro-phenyl ring and are twisted to each other, making a dihedral angle of 78.55 (13)°. In the crystal, weak C-H⋯O hydrogen bonds and C-H⋯π inter-action link the mol-ecules into a three-dimensional supra-molecular architecture.
