title: 3-Oxapentane-1,5-diyl dicarbamate.
abstract: The complete mol-ecule of the title compound, C(6)H(12)N(2)O(5), 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 mol-ecules into a three-dimensional supra-molecular architecture.
