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.
[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.
A close relative to tetramantane (a higher homologue of adamantane), its proper name is nonacyclo[11.7.1.1 12,18.0 3,16.0 4,13.0 5,10.0 6,14.0 7,11.0 15,20]docosane. Because its unusual ethano-bridge was a deviation from the standard hydrocarbon caged rearrangements, it came to be known as bastardane—the unwanted child. [3] [46] Dinocap
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:

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.
