Carbonyl and oxalyl bridged bis(1,5-diaminotetrazole)-based energetic salts.
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 ((1)H, (13)C, (15)N) NMR, elemental analyses, density, differential scanning calorimetry and impact sensitivity. 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.
