Synthesis, characterization, and energetic properties of 6-amino-tetrazolo[1,5-b]-1,2,4,5-tetrazine-7-N-oxide: a nitrogen-rich material with high density.

The synthesis and energetic properties of a novel N-oxide high-nitrogen compound, 6-amino-tetrazolo[1,5-b]-1,2,4,5-tetrazine-7-N-oxide, are described. Resulting from the N-oxide and fused rings system, this molecule exhibits high density, excellent detonation properties, and acceptable impact and friction sensitivities, which suggests potential applications as an energetic material. Compared to known high-nitrogen compounds, such as 3,6-diazido-1,2,4,5-tetrazine (DiAT), 2,4,6-tri(azido)-1,3,5-triazine (TAT), and 4,4',6,6'-tetra(azido)azo-1,3,5-triazine (TAAT), a marked performance and stability increase is seen. This supports the superior qualities of this new compound and the advantage of design strategy.
