Nitrogen-Rich Amino-triazolium Salts Based on Binary 4,5-Dicyano-1,2,3-triazolate (C₄N₅^-) Anion

A series of amino-triazolium salts based on 4,5-dicyano-1,2,3-triazolate (C₄N₅^-) anion were synthesized for first time by means of facile deprotonation reactions. The ionic compounds were characterized by single-crystal X-ray diffraction, vibrational spectroscopy, and elemental analysis. The thermal stability of the salts was assessed by differential scanning calorimetry, which showed good thermal stabilities up to above 180 °C. The heats of formation of these salts were computed using the methods of isodesmic reactions. In addition, the sensitivities of the studied salts toward impact and friction were determined, and all salts were found to be neither impact (> 40 J) nor friction sensitive (> 360 N).
