To examine the potential applications of nitrogen-rich heterocycle-based materials, a multifunctional 3-(5-amino-1,2,4-oxadiazol-3-yl)-1H-1,2,4-triazol-5-nitramide ligand with a coplanar configuration was provided, and then a series of its corresponding energetic metal salts were prepared and efficiently characterized. Potassium, cesium, and magnesium salts were further confirmed by using X-ray diffraction techniques. The crystal structures including the coordination modes and packing interactions of these three salts were analyzed. All newly prepared metal salts except EMS-6 exhibited good thermostability (Td > 236 °C) and remarkable insensitivity to mechanical stimulation (sensitivity to impact > 22.5 J, friction > 280 N), suggesting satisfactory safety performance. The constant-volume combustion energy of these eight salts was determined experimentally, and standard molar formation enthalpy (ΔfHmθ) at 298 K was calculated using Hess’s law. Upon their combustion, the three new formulations designed with EMS-1, EMS-7, and EMS-8 presented different shades of red colors, enabling them to be promising candidates for environment-friendly pyrotechnic components.

3-(5-氨基-1,2,4-恶二唑-3-基)-1H-1,2,4-三唑-5-硝酰胺的高能金属盐：环境友好型烟火元件的有前途的替代品
为了研究富氮杂环基材料的潜在应用，多功能3-(5-氨基-1,2,4-恶二唑-3-基)-1 H -1,2,4-三唑-5-硝酰胺提供了具有共面构型的配体，然后制备了一系列相应的含能金属盐并对其进行了有效表征。通过使用X射线衍射技术进一步证实了钾盐、铯盐和镁盐。分析了这三种盐的晶体结构，包括配位模式和堆积相互作用。除EMS-6外，所有新制备的金属盐均表现出良好的热稳定性（T d> 236 °C），并且对机械刺激显着不敏感（冲击敏感度 > 22.5 J，摩擦力 > 280 N），表明令人满意的安全性能。通过实验确定了这八种盐的定容燃烧能，并利用赫斯定律计算了 298 K 时的标准摩尔生成焓 (Δ f H m θ )。用EMS-1、EMS-7和EMS-8设计的三种新配方在燃烧时呈现出不同深浅的红色，使它们成为环境友好型烟火组件的有希望的候选者。
