摘要：
To obtain high-performance energetic materials, 3,5-diamino-1,2,4-triazole was utilized as a raw material to synthesize 3-hydrazinyl-5-amino-1H-1,2,4-triazolium dihydrochloride(compound 1)through diazotization and reduction reactions. A novel energetic ionic salt, 3-hydrazinyl-5-amino-1H-1,2,4-triazolium dinitrate(compound 2), was prepared by the metathesis reaction of compound 1 with silver nitrate. The structure of compound 2 was characterized using various techniques including FTIR, NMR, mass spectrometry, elemental analysis, and single-crystal X-ray diffraction. Thermal decomposition of compound 2 was studied by DSC and TG. The contribution of hydrogen bonding to the intermolecular interactions in the crystal of compound 2 was calculated using Crystal Explorer software. The detonation and safety properties of compound 2 were also investigated. The results show that compound 2 belongs to monoclinic crystal system with space group P2/n and cell parameters a=6.9296Å,b=9.9082Å,c=13.3696Å,α=90.00°,β=103.51(2)°,γ=90.00°,V=892.54(11)Å3. It exhibits excellent thermal stability with a thermal decomposition temperature of 189.7℃. Furthermore, compound 2 demonstrates outstanding detonation performance and low sensitivity, with detonation velocity and pressure values of 8673m/s and 32.5GPa, respectively. The friction sensitivity and impact sensitivity are 112N and 25J, respectively. © 2023 Zhengzhou Institute of Abrasives Grinding
