Ferric Azide, Basic

The preparation of ferric azide failed, however, due to the formation of basic ferric azide. A complex compound was obtained by Martin from chromium hydroxide and hydrazoic acid. It contained no chromium or N ions and has the probable formula of a complex compound [Cr(N3)4]H.

Earlier, Turrentine (Ref 4) obtained ferric azide in soln by electrolysis of a dil sodium azide soln using iron electrodes and later by Browne et al (Ref 6) on using iron electrodes in liq amm solns of ammonium azide, but the product was ammonolyzed to an Ammono-Basic Ferric Azide. Curtius et al (Refs 1 2), with ferric alum and NaN, obtained ferric azide in soln and they also repotted that iron dissolved in dil aq hydrazoic acid to form the azide, but the soln decompd on evapn giving either the basic azide or hydroxide. In 1934 Franklin (Ref 9) noted that aq hydrazoic acid reacts on iron to form ferric azide, nitrogen and ammonia together with a small amt of hydrazine. According to Franklin Ferrous Azide, Fe(Nj), is formed first and oxidizes to ferric azide when the soln is warmed with excess hydrazoic acid present. Ricca (Ref 11) studied the reactions of the ferric ion with hydrazoic acid on electrolysis of their solns and obtained results which would indicate that ferric azide has the structure [Fe(Nj)](Nj)2...
