In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]
The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.

Methyl azide can be prepared by the methylation of sodium azide, for instance with dimethyl sulfate in alkaline solution, followed by passing through a tube of anhydrous calcium chloride or sodium hydroxide to remove contaminating hydrazoic acid. [1] The first synthesis was reported in 1905. [2] Decomposition to a nitrene is a first-order reaction:
[1] The cyclic form was identified in 2003 by N. Hansen and A. M. Wodtke using ultraviolet photolysis of chlorine azide. Although the reaction yielded mostly the linear form, about 20% of the molecules were cyclic. [4] [1] The ring has C 2v symmetry [1] —an isosceles triangle—in contrast to the linear form that has equal N–N bond-lengths.
In chemistry, a nitride is a chemical compound of nitrogen.Nitrides can be inorganic or organic, ionic or covalent.The nitride anion, N 3-ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring.
In chemistry, the pentazenium cation (also known as pentanitrogen) is a positively-charged polyatomic ion with the chemical formula N + 5 and structure N−N−N−N−N.Together with solid nitrogen polymers and the azide anion, it is one of only three poly-nitrogen species obtained in bulk quantities.
In its most characteristic reaction, the solid decomposes explosively, releasing nitrogen gas: 2 AgN 3 (s) → 3 N 2 (g) + 2 Ag(s). The first step in this decomposition is the production of free electrons and azide radicals; thus the reaction rate is increased by the addition of semiconducting oxides. [4]
