We describe the structure and properties of [Zn(CHN)N] , a new nonporous three-dimensional high-energy metal-organic framework (HE-MOF) with enhanced thermal stability. The compound is synthesized by the hydrothermal method with in situ ligand formation under controlled pH and characterized using single-crystal X-ray diffraction, elemental analysis, and Fourier transform infrared. The measured detonation temperature ( = 345 °C) and heat of detonation (Δ = -0.380 kcal/g) compare well with commercial explosives and other nitrogen-rich HE-MOFs. The velocity and pressure of denotation are 5.96 km/s and 9.56 GPa, respectively. Differential scanning calorimetry analysis shows that the denotation of [Zn(CHN)N] occurs via a complex temperature-dependent mechanism.
我们描述了[Zn(CHN)N]的结构和性质，它是一种新型的无孔三维高能金属有机框架（HE-MOF），具有增强的热稳定性。该化合物通过水热法在可控pH值下原位形成配体进行合成，并使用单晶X射线衍射、元素分析和傅里叶变换红外光谱进行表征。测得的爆轰温度（= 345°C）和爆轰热（Δ = -0.380 kcal/g）与商业炸药和其他富氮HE-MOFs相比具有良好的性能。爆轰速度和压力分别为5.96 km/s和9.56 GPa。差示扫描量热分析表明，[Zn(CHN)N]的爆轰通过复杂的温度依赖机制发生。
