Nitrogen‐rich 3, 4‐bis(1 H ‐tetrazol‐5‐yl)furoxan (H 2 BTF, 2 ) and its energetic salts with excellent thermal stability were successfully synthesized and fully characterized by 1 H, and 13 C NMR, and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses. Additionally, the structures of barium ( 3 ) and 1‐methyl‐3, 4, 5‐triamino‐triazolium ( 10 ) salts were confirmed by single‐crystal X‐ray diffraction. The densities of the energetic salts paired with organic cations range between 1.56 and 1.85 g · cm –3 as measured by a gas pycnometer. Based on the measured densities and calculated heats of formation, the detonation pressures and velocities are calculated to be in the range 23.4–32.0 GPa and 7939–8915 m · s –1 , which make them competitive energetic materials.
