Energetic Ethylene‐ and Propylene‐Bridged Bis(nitroiminotetrazolate) Salts

This is the authors' abstract. We don't add key points for this paper.

High energy density materials with ethylene- and propylene bis(5-nitroiminotetrazolate) as the anions are reported; all salts were fully characterized by IR, and (1)H, (13)C, and (15)N NMR spectroscopy as well as elemental analyses. In addition, the heats of formation (DeltaH(f)) and the detonation pressures (P) and velocities (D) were calculated.The synthesis and detonation properties of high energy density materials with ethylene- and propylene bis(nitroiminotetrazolate) as the anions are reported; all salts were fully characterized by IR, and (1)H, (13)C, and (15)N NMR spectroscopy as well as elemental analyses. In addition, the heats of formation (DeltaH(f)) were calculated with the Gaussian 3.0 suite of programs. By using the experimental values for the densities of the nitroiminotetrazolate salts, the detonation pressures (P) and velocities (D) were calculated using Cheetah 5.0.
