N2 - Five energetic salts of 3,6-bishydrazino-1,2,4,5-tetrazine (BHT), namely (BHT)2(NTO)3 (3), (BHT)(BTT)·2H2O (4), (BHT)(DNP)2 (5), (BHT)(NATr)2 (6), and (BHT)(FOX-7)2 (7), were synthesized and fully characterized by elemental analysis, FT-IR, and mass spectra. The crystal structures of salts 3 and 4 were obtained and determined. Sensitivities towards outside stimuli and thermal behaviors of all the compounds were investigated, besides, thermodynamics of both 3 and 4 were calculated as well. The compounds 3–7 exhibit splendid thermal stabilities and satisfactory sensitivities simultaneously. Notably, unlike the previously known layered packing, compound 4 was found to adopt an unusual layered crystal packing with arch layers alternately arranged upward or downward. It may play an important role in contributing to its superior thermal stability (350 °C), providing an enlightening thinking to design new highly thermal stable energetic materials.
