Mercury II Azide

Both cadmium azide and mercury(II) azide are sensitive explosives, and no attempts have been made to determine optimum crystal-growth parameters for them. Precipitation studies have shown that large cadmium azide particles are more sensitive than smaller ones. Deb [33] has succeeded in preparing thin films by a displacement reaction. This is accomplished by evaporating successive thin films of an alkali-metal azide and the corresponding halide. Better-quality films 

Favorable crystal-growth techniques have been determined for many of the azide compounds. However, there remains much work to be done in characterizing the degree of crystal perfection and impurity content. 

Only one study, on NaNa, has addressed the problem of crystal perfection and crystalline stoichiometry [7]. This revealed the presence of anion vacancies, a consequence of hydrolytic decomposition. Since most azides are grown from solutions, this result may well carry over to other azides.

This following article was sent to Strike by Osmium and Feck (are they the same person ). It involves the direct addition of azide to a terminal alkene (you-know-who) by the in situ production of the reactant mercury (II) azide from mercuric acetate and sodium azide (please don t ask) [80]. 

Interaction, without addition of acid, produces tetrazolylguanidine ( tetrazene ), a primary explosive of equal sensitivity to mercury(II) azide, but more readily initiated.

One of the methods for the synthesis of alkyl azides is based on the regioselective addition of mercury(II) azide, generated from mercury(II) acetate and sodium azide, to alkenes in water/te-trahydrofuran (1 1) to afford /i-azidoalkylineiciiry compounds which are then reductively demercurated to alkyl azides5-7. Completely diastereoselective cis addition occurred with norbornene (exo addition)5 and cyclopropenes6. 

Caution It is important to add the mercury(II) acetate to the solution of NaN3 in THF/H20 and not vice versa. Nevertheless, one explosion occurred in the mercury(II) azide addition to norbornene. 

Solvent extraction of the slightly ionized mercury (II) azide complex, HgNs, or neutral Hg(N3)2 in the pH range 4-6 has been investigated. With n-butanol the distribution coefficient is 10.6 at 25°C. The complex obeys Beer s law at 248 nm in both aqueous and butanol solution [23]. 

Among complex mercury(II) azides a colorless, explosive dipyridine diazido-mercury(II) of the possible structure [Hg (Py)2(N3)2] is precipitated when water is added to a solution of mercury(II) nitrate in pyridine [138]. A triazidomercurate(II), [Hg (N3)3] , is obtained from mercury(II) nitrate and excess sodium azide in acid media and isolated as the tetraphenylphosphonium salt [139,222,238].
