The synthesis of 3-nitroguanidino-1,2,4-triazolo[4.3-b]-s-tetrazine and its salts with triaminoguanidine,diaminoguanidine, ammonia, and silver has been carried out in two steps, starting from the readily available 3-(3,5-dimethylpyrazol-1-yl)-1,2,4-triazolo[4.3-b]-stetrazine. The new energetic compounds have been identified by FTIR, 1H, 13C NMR spectroscopy, LC-MS and elemental analyses. The thermal decomposition behavior was studied by differential scanning calorimetry. The combustion of hydrazinium and triaminoguanidinium salts of 1,2,4-triazolo[4.3-b]-stetrazine has been studied in a constant-pressure bomb in the pressure interval of 0.1-10MPa and compared with that of well-known polynitrogen compound BTATz. The salts demonstrated similar burning rates while having lower pressure exponent.
