New energetic transitionmetal (Co, Cu, Zn, and Cd) coordination compounds (CCs) based on versatile and multifunctional 1-amino-tetrazol-5-one ligand were prepared by using a facile strategy. All the synthesized CCs were characterized by single-crystal X-ray diffraction. They crystallize in common space groups with high densities in the range of 2.246 to 2.598 g·cm−3 and their onset decomposition temperatures
使用简便的策略制备了基于多功能和多功能 1-氨基-四唑-5-one 配体的新型高能过渡金属(Co、Cu、Zn 和 Cd)配位化合物 (CCs)。所有合成的 CC 均通过单晶 X 射线衍射表征。它们以 2.246 至 2.598 g·cm -3范围内的高密度在公共空间群中结晶,并且发现它们的起始分解温度范围为 292 °C ( CC1 ) 至 327 °C ( CC3 ))。进一步的研究表明,除了配位键之外,还存在强氢键相互作用,这最终决定了所得 CCs 的晶体结构工程和物理性质。使用标准方法评估对冲击和摩擦的机械敏感性,因此,高能金属 CC 被归类为不敏感。这些高能金属 CC 的火焰测试显示出从浅蓝色到蓝绿色的一系列特征火焰颜色,除了镉配位化合物,表明无色火焰。因此,这些 CC 对冲击和摩擦的不敏感性以及特征火焰颜色支持它们作为不敏感的高能材料或烟火的潜在用途。

A hyper conjugated structure, picrylchloride functionalized 1‐picrylamino‐tetrazol‐5‐one, was synthesized by a nucleophilic substitution reaction. The single crystals of 1‐picrylamino‐tetrazol‐5‐one were cultured and determined by X‐ray single‐crystal diffractometer. The thermal behavior was investigated by differential scanning calorimetry (DSC) and thermogravimetry‐derivative thermogravimetry (TG‐DTG)
our effort to seek for the “green” energetic coordination polymers (CPs), a versatile and multifunctional 1-amino-tetrazol-5-one ligand was synthesized and its complexes with a series of alkaline and earth alkaline metals were prepared and comprehensively characterized. A broad range of differently shaped 1D, 2D, and 3D supramolecular structures for the prepared energetic compounds were found, where
