The synthesis of three neutral 3,3'-di(1,2,5-oxadiazol-3-yl)-5,5'-bi(1,2,4-oxadiazole) structures in combination with different energetic moieties such as nitramino, trinitroethylamino, and N-nitrated trinitroethylamino is presented. In addition, a novel family of energetic salts based on 4,4'-([5,5'-bi(1,2,4-oxadiazole)]-3,3'-diyl)-bis(1,2,5-oxadiazol-3-nitramide) is synthesized. The new compounds (4, 6-18) are characterized by IR and multinuclear NMR spectroscopy and elemental analysis. The structures of 4⋅2 C4 H8 O2 , 9, 13, 15, and 16 are further confirmed by single-crystal X-ray diffraction studies. The thermal stabilities of 4 and 6-18 are determined by differential scanning calorimetry. Most of the new compounds have high densities (1.72-1.93 g cm-3 ) measured using a gas pycnometer (25 °C). Energetic evaluation indicates that they also have good detonation pressures and velocities (P: 26.4-41.9 GPa; D: 8218-9550 m s-1 ).

将高能部分并入四个恶二唑环系统中，以生成高性能高能材料。

三种中性3,3'-二（1,2,5-恶二唑-3-基）-5,5'-二（1,2,4-恶二唑）结构与不同的高能基团（如硝胺基）的合成提出了三硝基乙基氨基，N-硝化的三硝基乙基氨基。此外，基于4,4'-（[[5,5'-bi（1,2,4-恶二唑）]-3,3'-二基）-bis（1,2,5 -恶二唑-3-硝酰胺）的合成。新化合物（4，6-18）的特征在于红外光谱，多核NMR光谱和元素分析。通过单晶X射线衍射研究进一步证实了4⋅2C4 H8 O2，9、13、15和16的结构。4和6-18的热稳定性通过差示扫描量热法确定。大多数新化合物具有使用气体比重瓶（25°C）测量的高密度（1.72-1.93 g cm-3）。
