Characterization, crystal structure of 2,4-bis(triphenylphospanimino)tetrazolo[5,1-a]-[1,3,5]triazine, and improved crystal structure of 2,4,6-triazido-1,3,5-triazine

2,4-Bis(triphenylphosphanimino)tetrazolo[5,1-a][1,3,5]triazine (1) was synt hesized by reaction of cyanuric azide with triphenylphosphane. 1 is charact erized by X-ray structural analysis, IR, Raman, and NMR spectroscopy The ob tained spectra showed that the remaining azide group in 1 reacts with, the N4 atom of the triazine ring and forms a tetrazole. An improved crystal str ucture for 2,4,6-triazido-1,3,5-triazine (2) was determined and for the fir st time a N-14-NMR spectrum was obtained. CAUTION: 2 (Cyanuric azide) is ex plosive! The explosive nature increases with greater purity and crystal siz e.
