The complete mol­ecule of the title compound, C6H12N2O5, is generated by a rotation about a twofold axis. The conformation along the bond sequence linking the two amino groups is trans-trans-(+)gauche-trans-trans. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional supra­molecular architecture.
