Zn(N 3) 2 crystallizes in three different polymorphs α-Zn(N 3) 2 and the labile β-Zn(N 3) 2 and γ-Zn(N 3) 2 forms. [40] The first mercury (I) azide was realized by Curtius in 1890 by combining aqueous mercury(I) salts with alkali metal azides and by combining HN 3 with elemental mercury to produce Hg 2 (N 3) 2.
The oxygen diazide O(N 3) 2 has been suggested to be the intermediate in the formation of cyclic nitrous oxide N 2 O from OF 2 and NaN 3, but its existence has not yet been confirmed. [70] The parent sulfur azides S(N 3) 2 or S(N 3) 4 have not been synthesized and only theoretical calculations to their existence have been studied. [71]
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]
Iron(III) azide, also called ferric azide, is a chemical compound with the formula Fe(N 3) 3. It is an extremely explosive, impact-sensitive, hygroscopic dark brown solid. This compound is used to prepare various azidoalkanes, such as n -butyl azide, from alkenes via formation of alkylboranes and subsequent anti-Markovnikov addition of azide group.
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.
[2] [3] The linear form of N 3 was discovered in 1956 by B. A. Thrush [4] by photolysis of hydrogen azide. [5] As a linear and symmetric molecule, it has D ∞h symmetry, with a nitrogen–nitrogen bond length averaging 1.8115 Å. The first excited electronic state, A 2 Σ u, is 4.56 eV above the ground state. [1]
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] Pure silver azide explodes at 340 °C, but the presence of impurities lowers this down to 270 °C. [5]
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.
