Hydrazinium is the cation with the formula [N2H5+. This cation has a methylamine-like structure ([H2N−NH3+). It can be derived from hydrazine by protonation (treatment with a strong acid). Hydrazinium is a weak acid with pKa = 8.1.
Salts of hydrazinium are common reagents in chemistry and are often used in certain industrial processes. [1] Notable examples are hydrazinium hydrogensulfate, N2H6SO4 or [N2H5+[HSO4−, and hydrazinium azide, N5H5 or [N2H5+[N3−. In the common names of such salts, the cation is often called "hydrazine", as in " hydrazine sulfate" for hydrazinium hydrogensulfate.
The terms "hydrazinium" and "hydrazine" may also be used for the doubly protonated cation [N2H62+, more properly called hydrazinediium or hydrazinium(2+). This cation has an ethane-like structure ([H3N−NH32+). Salts of this cation include hydrazinediium sulfate [N2H62+[SO42− [2] and hydrazinediium bis(6-carboxypyridazine-3-carboxylate), [N2H62+([C6H3N2O4−)2. [3]
