target compounds have high heats of formation ranging from 1.40 to 2.84 kJ g−1. Among them, the safety and detonation performances of 6 (D: 8747 m s−1, P: 33.0 GPa, Td: 238.2 °C, IS: 30 J) and energetic salts dihydroxylammonium((4-nitro-1H-pyrazole-3,5-diyl)bis(1H-1,2,4-triazole-5,3-diyl))bis(nitroamide) (9) (D: 9077 m s−1, P: 33.6 GPa, IS: >40 J) and dihydrazinium((4-nitro-1H-pyrazole-3,5-diyl)bis(1H-1
获得了新的对称的(4-硝基-1 H-吡唑-3,5-二基)双(1 H -1,2,4-三唑)基衍生物家族。所有这些新化合物均通过(1 H,13 C)NMR光谱,红外光谱,元素分析和差示扫描量热法(DSC)进行表征。5,5'-(4-硝基-1 H-吡唑-3,5-二基)双(3-硝基-1 H -1,2,4-三唑)(6)和N,N'-的结构((4-硝基-1 H-吡唑-3,5-二基)双(1 H -1,2,4-三唑-5,3-二基))二乙酰胺(7通过单晶X射线衍射进一步证实了)。另外,使用高斯09软件包的理论计算表明目标化合物具有1.40至2.84 kJ g -1的高形成热。其中,6(D:8747 ms -1,P:33.0 GPa,T d:238.2°C,IS:30 J)和高能盐二羟基铵((4-硝基-1 H-吡唑- 3,5-二基)双(1 H -1,2,4-三唑-5,3-二基))双(硝基酰胺)(9)(D:9077
