1,1′-Azobis(tetrazole): A Highly Energetic Nitrogen-Rich Compound with a N₁₀ Chain

The reaction of 1-aminotetrazole with acidic sodium dichloroisocyanurate allowed isolation of 1,1′-azobis(tetrazole). The rare chain of 10 nitrogen atoms in this compound was confirmed by X-ray crystallography, and the physical and explosive properties of the azo compound were characterized. The title compound possesses both exceedingly high explosive performance and sensitivity.
