Nitrogen‐Rich Energetic Monoanionic Salts of 3,4‐Bis(1 H‐5‐tetrazolyl)furoxan

Abstract 3,4‐Bis(1 H ‐5‐tetrazolyl)furoxan (H 2 BTF, 2 ) and its monoanionic salts that contain nitrogen‐rich cations were readily synthesized and fully characterized by multinuclear NMR ( 1 H, 13 C) and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses. Hydrazinium ( 3 ) and 4‐amino‐1,2,4‐triazolium ( 7 ) salts crystallized in the monoclinic space group P 2(1)/n and have calculated densities of 1.820 and 1.764 g cm −3 , respectively. The densities of the energetic salts range between 1.63 and 1.79 g cm −3 , as measured by a gas pycnometer. Detonation pressures and detonation velocities were calculated to be 23.1–32.5 GPa and 7740–8790 m s −1 , respectively.
