Bis(hydrazinium) N,N'-Dinitroethylenediaminate(2 -)

The title compound, 2N₂H₅⁺.C₂H₂N₄O₄^2-, is an inherently insensitive high-energy material. The anion has C_i 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.
