Abstract Synthesis, characterization, and thermolysis studies of 1‐amino‐1‐hydrazino‐2,2‐dinitroethene ( 2 ) and salts thereof are reported. These compounds have been fully characterized by IR and NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC), density, and impact sensitivity measurements. Compound 2 decomposes at 124.5 °C (DSC) and the salts decompose over the range 138.6–181.6 °C, thus showing higher thermostability. The calculated detonation pressures ( P ) for these salts range from 27.2 to 37.8 GPa, and detonation velocities ( vD ) fall between 8424 to 9482 m s −1 ; these properties make them competitive energetic materials.
