The energetic derivatives of nitrogen-rich 3,4,5-triamino-1-tetrazolyl-1,2,4-triazolium (TATT) cation combined with nitrate (1), chloride (2) and perchlorate (3) anions were synthesized from the reaction of 3,4,5-triamino-1-tetrazolyl-1,2,4-triazole with various acids. All salts were characterized by IR, NMR and elemental analysis. Their structures were verified by single-crystal X-ray diffraction. Salt 1 crystallizes in the monoclinic system P21/c. Salt 2 and 3 crystallize in the triclinic system P-1. Both theoretical and experimental methods demonstrate these compounds having positive heats of formation. Their sensitivities to impact and friction were also determined.
