摘　　要：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 energetic coordination complex of [Mn（AZT）2（H2O）4]（HTNR）2·4H2O（AZT=3-azido-1,2,4-triazole,HTNR=2,4,6-trinitro resorcinol） was prepared by the reaction between the acidic manganese（Ⅱ） salt of 2,4,6-trinitro resorcinol and AZT in an aqueous solution.The complex was characterized by elemental analysis and FTIR spectroscopy.The molecular structure was determined by X-ray single crystal diffraction.The crystal belongs to the triclinic system with a P1 space group.The central manganese（Ⅱ） cation has a slightly distorted octahedron feature.Three-dimension networks were formed and the layers are linked by extensive hydrogen bonding.The thermal decomposition mechanism of [Mn（AZT）2（H2O）4]（HTNR）·24H2O was predicted based on differential scanning calorimetry（DSC） and thermogravimetry-derivative thermogravimetry（TG-DTG） analyses.One endothermic peak and three exothermic peaks are present during the thermal decomposition process with the final residue at 600 ℃ being MnO and MnO2.The kinetic parameters of the exothermic process for the complex were studied using Kissinger＇s and Ozawa-Doyle＇s methods.Furthermore,impact sensitivity,flame sensitivity,and friction sensitivity tests reveal that the title complex is sensitive and selective towards external stimulants.
