The title compound, 2N2H5+.C2H2N4O42-, is an inherently insensitive high-energy material. The anion has Ci symmetry and is almost planar. The nitrate groups are asymmetric, with a mean nitrate N-O distance longer than that found in N,N'-dinitroethylenediamine and an N1-N2 distance close to a double-bond value.
