通过酸性2,4,6-三硝基间苯二酚(HTNR)的锰盐与3-叠氮-1,2,4-三唑(AZT)在水溶液中反应,制备得到一种新颖的锰配合物[Mn(AZT)2(H2O)4](HTNR)2·4H2O.通过元素分析和红外光谱对配合物进行了表征,用X射线单晶衍射分析确定其晶体结构.该配合物为三斜晶系,空间群为P1,中心锰(Ⅱ)离子为六配位的畸变的八面体结构,分子内和分子间强烈的氢键作用构成了有序的三维(3D)网状结构.采用差示扫描量热(DSC)和热重-微分热重(TG-DTG)分析技术研究了配合物的热分解特性,并预测了它的热分解反应机理.利用Kissinger方法和Ozawa-Doyle方法研究了其第一放热分解峰的分解动力学过程.其分解过程包括一个吸热峰和三个放热峰,在600℃的分解产物为MnO和MnO2的混合物.同时.对这个配合物进行了感度(撞击感度、火焰感度、摩擦感度)性能分析,结果表明,它对外界刺激具有很强的响应性和选择性.
A novel manganese (Mn) was prepared by reaction of acidic 2,4,6-trinitro-resorcinol (HTNR) manganese salt with 3-azido-1,2,4-triazole (AZT) in aqueous solution The complex was characterized by elemental analysis and infrared spectroscopy, and its crystal structure was confirmed by X-ray single crystal diffraction analysis. The complex was tri The orthorhombic, space group P1 and the center manganese (Ⅱ) ion are hexahedral distorted octahedron structures, and the intramolecular and intermolecular hydrogen bonds form an ordered three-dimensional (3D) network. The thermal decomposition characteristics of the complex were investigated by differential scanning calorimetry (DSC) and thermogravimetric-differential thermal analysis (TG-DTG), and its thermal decomposition reaction mechanism was predicted. Using Kissinger method and Ozawa-Doyle method The decomposition kinetics of its first exothermic decomposition peak is shown in Figure 1. The decomposition process includes one endothermic peak and three exothermic peaks and the decomposition product at 600 ℃ is a mixture of MnO and MnO2.At the same time, Sensitivity (impact sensitivity, flame sensitivity, friction sensitivity) performance analysis, the results show that it has strong external stimuli responsiveness and selectivity.
