摘要
A novel nonmetallic salt,3,5,7-triamino[1,2,4]triazolo[4,3-a][1,3,5]triazine pentazolate(4),was synthesized through a metathesis reaction by employing AgN5 as precusor with 3,5,7-triamino[1,2,4]triazolo[4,3-a][1,3,5]triazine hydrochloride. The structural characterization were carried out by X-ray single crystal diffraction,infrared spectroscopy(IR),elemental analysis(EA),nuclear magnetic resonance(NMR),and thermal decomposition behavior were determined by thermogravi-metric analysis(TG)and differential scanning calorimetry(DSC). The enthalpy of formation of compound 4 was calculated using atomization method,the detonation performance was predicted using EXPLO5,and sensitivity was tested using BAM testing method. The results show that compound 4 exhibits a monoclinic crystal structure with a crystal density of 1.644 g·cm-3 and belongs to the P21/n space group. This compound has a nitrogen content of 77%,a thermal decomposition temperature of 113.8 ℃ ,and an enthalpy of formation of 491.5 kJ·mol-1. Furthermore,its detonation velocity was calculated at 7913 m·s-1,detonation pressure at 19.6 GPa;The impact sensitivities measured were >40 J,and friction sensitivity >360 N. © 2024 Institute of Chemical Materials, China Academy of Engineering Physics.
