In this study, a series of energetic compounds based on C–C linked 1,2,3-triazole and 1,2,4-triazole were synthesized and characterized, i.e., 5-(5-nitro-2H-1,2,3-triazole-4-yl)-4H-1,2,4-triazole-3,4-diamine (compound 1), N-(3-amino-5-(5-nitro-2H-1,2,3-triazole-4-yl)-4H-1,2,4-triazole-4-yl) nitramide (compound 4), and their energetic salts (compounds 2, 3, 5, and 6). The structures of compounds 1, 2, and 4 were determined by X-ray diffraction. All the new compounds feature acceptable thermal stability (T_dec ​= ​185–266 ​°C), with thermal decomposition temperature higher than that of RDX (T_dec ​= ​204 ​°C) except for compound 6 (T_dec ​= ​185 ​°C). Moreover, the detonation velocities of compounds 5 and 6 are 9200 ​m·s⁻¹ and 9024 ​m·s⁻¹, respectively, which are higher than that of RDX (D ​= ​8795 ​m·s⁻¹). Furthermore, the new compounds show low mechanical sensitivity (IS ​= ​20 ​J, FS ​= ​240 ​N) compared to RDX (IS ​= ​7.4 ​J, FS ​= ​120 ​N). These results will help to accelerate the development of new high-energy density materials.

本研究合成并表征了一系列基于 C-C 连接的 1,2,3-三唑和 1,2,4-三唑的含能化合物，即5-(5-nitro-2H-1,2, 3-triazole-4-yl)-4H-1,2,4-triazole-3,4-diamine (compound 1 ), N-(3-amino-5-(5-nitro-2H-1,2,3) -triazole-4-yl)-4H-1,2,4-triazole-4-yl) 硝酰胺（化合物4）及其含能盐（化合物2、3、5和6）。化合物的结构1，2，和4通过X射线衍射确定。所有新化合物都具有可接受的热稳定性（T _dec = 185–266 °C)，热分解温度高于RDX ( T _dec  = 204 °C)，除了化合物6 ( T _dec  = 185 °C)。此外，化合物5和6的爆速分别为9200 m·s ^-1和9024 m·s ^-1，高于RDX（D  = 8795 m·s ^-1）。此外，与RDX（IS = 7.4 J，FS = 120 N）相比，新化合物显示出较低的机械灵敏度（IS = 20 J，FS = 240 N）。这些结果将有助于加速新型高能量密度材料的开发。
