A new oxygen-rich energetic salt dihydrazine tetranitroethide: a promising explosive alternative with high density and good performance.

A novel high-energy salt with good oxygen balance, dihydrazine tetranitroethide (5), has been synthesized and characterized by FT-IR spectroscopy, NMR spectroscopy, elemental analysis, and X-ray single crystal diffraction. Compound 5 exhibits high crystal density (1.81 g cm -3 ) and impressive detonation velocity (9508 m s -1 ) and detonation pressure (37.9 GPa), showing potential applications as a high performance explosive and a promising additive of propellants.
