The amination of 1,5‐diamino‐1,2,3,4‐tetrazole with tosylhydroxylamine yielded 1,4,5‐triaminotetrazolium tosylate. Metathesis reactions yielded energetic bromide, nitrate, and nitrotetrazolate 2‐oxide salts. Owing to the exceedingly high nitrogen content of the cation (>84 % !), the calculated heats of formation and the experimental explosive and thermal sensitivities are exceedingly high. For the first time, the X‐ray structure of this energetic cation is reported, as are the standard multinuclear NMR, infrared, and Raman spectroscopic data. Explosive performances (detonation velocity and pressure) have also been calculated for a sample compound.
