Salts of 3,5-dinitro-1 H -1,2,4-triazole, a building block for energetic materials, have been prepared and fully characterized. Most of the studied salts exhibit high thermal stability and very low shock and friction sensitivities. 3,5-Dinitro-1,2,4-triazolates with the nitrogen-rich ammonium, guanidinium, aminoguanidinium, and aminotetrazolium cations are energetic and have potential for energetic material applications. Salts containing alkali, alkali earth metal, and silver cations exhibit coloured emissions upon combustion while salts with large organic cations such as PPh 4 + and (Ph 3 P) 2 N + are highly insensitive and can be easily crystallized. Several novel salts with the energetic 3,5-dinitro-1,2,4-triazolate (DNT) anion have been prepared and characterized.
