摘要

Ionic derivatives of 4,4',5,5'-tetranitro-2,2'-biimidazole (TNB1) are of growing interest to many researchers these days. Amongst the others, there is 3,5-diamino-1,2,4-triazolium 4,4',5,5'-tetranitro-2,2'-biimidazolate (DATNBI) The salt can be easily prepared from widely available substrates. After filtration and drying, it shows no signs of hygroscopicity and decomposes at 239 °C. The structure of obtained compound was confirmed with NMR spectroscopy and elemental analysis. Thermal properties were investigated with DTA/TG analysis. We also determined standard enthalpy of formation. Detonation parameters were calculated with CHEETAH code for density determined for pressed sample. Some of the energetic properties were measured experimentally.
