Hydrazinium nitrate

The monoprotonated hydrazinium cation in the title compound, N₂H₅⁺·NO₃^-, forms several types of hydrogen bonds. Stronger ones, in which the H atoms attached to the protonated N atom take part, link cations and anions into layers. Less strong hydrogen bonds, with participation of H atoms attached to the non-protonated N atom, link the layers into a three-dimensional structure. In addition to hydrogen bonds, short contacts of 2.8607 (10) Å have been found between O and N atoms of neighbouring nitrate anions. Such contacts can correspond to a weak inter­molecular inter­action similar to that in organic compounds containing nitro groups.
