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 dominant application of azides is as a propellant in ...
Main group azido compounds are chemical compounds consisting of azide, N 3-bonded to a main group element. [1] [2]Azido compounds are often shock sensitive.Their sensitivity correlates with the amount of ionic or covalent character the azide-element bond has, with ionic character being far more stable than covalent character. [3]
Reactivity studies of azide compounds are relatively limited due to how sensitive they can be. The sensitivity of these compounds tends to be correlated with the amount of ionic or covalent character the azide-element bond has, with ionic character being far more stable than covalent character. [3]
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.
Pentaazidoiron (III) ion [Fe(N 3) 5] 2-can be made by treating iron(III) salts with sodium azide. [ 26 ] [ 27 ] An iron azide reagent can be generated in situ . [ 28 ] NaN 3 and iron (III) sulfate Fe 2 (SO 4 ) 3 are combined in methanol and added to an organoborane followed by slow addition of 30% hydrogen peroxide, presumably forming Fe(N 3 ) 3 .
The bond order itself is the number of electron pairs (covalent bonds) between two atoms. [3] For example, in diatomic nitrogen N≡N, the bond order between the two nitrogen atoms is 3 (triple bond). In acetylene H–C≡C–H, the bond order between the two carbon atoms is also 3, and the C–H bond order is 1 (single bond).

Caesium azide can be prepared from the neutralization reaction between hydrazoic acid and caesium hydroxide: [4] CsOH + HN 3 → CsN 3 + H 2 O. Caesium carbonate can also be used as the base: Cs 2 CO 3 + HN 3 → CsN 3 + CO 2 + H 2 O. Caesium sulfate reacts with barium azide to form insoluble barium sulfate and caesium azide: Cs 2 SO 4 + Ba(N 3 ...
