Carbonyl and Oxalyl Bridged Bis(1,5-Diaminotetrazole)-Based Energetic Salts

摘要

High density energetic salts containing nitrogen rich cations and carbonyl- or oxalylbis(diamino-tetrazole) anions, which were obtained from cyanogen azide and hydrazine, were readily synthesized. In every case, a new family of energetic salts 3–14 were characterized by vibrational spectroscopy, multinuclear (1H, 13C, 15N) NMR, elemental analyses, density, differential scanning calorimetry and impact ensitivity. Compound 12 was structured by single crystal X-ray diffraction. The densities of 3-14, determined by gas pycnometer, range between 1.500 and 1.676 g cm~(-3). The heats of formation and detonation properties for these stable salts were calculated by using Gaussian 03 and Cheetah 5.0, respectively.
