In the title compound, C18H28N2O4, the mol-ecule displays a partially eclipsed conformation with an N - C - C - N torsion angle of 67.93 (s.u.?) ° linking the two ethoxy-carbonyl-cyclo-pentenyl groups. This conformation is different from the staggered conformation observed in the related N,N′-ethyl-enediamine with a cyclo-alkene residue. Mol-ecules are linked by two different N - H⋯O hydrogen bonds, generating sheets parallel to the (110) plane.
