Tetrazole Azasydnone (C2N7O2H) And Its Salts: High‐Performing Zwitterionic Energetic Materials Containing A Unique Explosophore

This work reports the first compound containing both a tetrazole and an azasydnone ring, a unique energetic material. Several energetic salts of the tetrazole azasydnone were synthesized and characterized, leading to the creation of new secondary and primary explosives. Molecular structures are confirmed by 1H and 13C NMR, IR spectroscopy, and X‐ray crystallographic analysis. The high heats of formation, fast detonation velocities, and straight‐forward synthesis of energetic azasydnones should capture the attention of future energetics research. Tetrazole azasydnone, an exciting new “green” primary explosive! A lead‐free compound and its silver salt are potential replacements for primary explosives.
