1,1'-Azobis(1H-tetrazole) was synthesized from 1-amino-1H-tetrazole by T. M. Klapötke and D. G. Piercey at the Ludwig Maximilian University of Munich in 2011. It contains an unprecedented 10–nitrogen atom chain. As might be expected from its structure, 1,1'-azobis(1H-tetrazole) is a powerful explosive, with a detonation velocity of almost 9200 m/s. Its extreme sensitivity to motion makes it impossible to handle as a dry solid; and in solution, it decomposes slowly with the release of nitrogen gas.
