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 ...
Trinitrogen also known as the azide radical is an unstable molecule composed of three nitrogen atoms. Two arrangements are known: a linear form with double bonds and charge transfer, and a cyclic form. Both forms are highly unstable, though the linear form is the more stable of the two. [1]
Sodium azide is an ionic solid.Two crystalline forms are known, rhombohedral and hexagonal. [1] [6] Both adopt layered structures.The azide anion is very similar in each form, being centrosymmetric with N–N distances of 1.18 Å.
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]
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 .
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Gold(III) azide is known as the tetraethylammonium salt [Et 4 N][Au(N 3) 4] and also adopts a square planar structure. [30] However unlike the silver azide, the gold azide is not stable at room temperature and will decompose after a few days and its metal azide bonds have significant covalent character.
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.
