摘　　要：合成了新型含能配合物[Co(AZT)2(H2O)4](HTNR)2·4H2O(AZT=3-叠氮-1,2,4-三唑,HTNR=酸式三硝基间苯二酚),并用元素分析(EA)和傅立叶变换红外光谱(FT-IR)对其进行了表征.采用缓慢蒸发溶剂法培养得到配合物单晶,用X射线单晶衍射仪进行了结构测定,该晶体属于三斜晶系,空间群为P1,晶胞参数:a=7.1824,b=10.1812,c=13.115,α=98.046°,β=105.367°,γ=104.103°,V=875.23,Z=1.采用差示扫描量热分析(DSC)和热重-微分热重分析(TG-DTG)研究了目标配合物的热分解过程,结合分解产物的红外光谱分析,提出了其热分解机理.用Kissinger,Starink和Ozawa三种多重扫描速率方法对第一放热分解过程的非等温动力学进行了分析,求得的活化能分别为124.53,124.82和125.55kJ·mol-1,三种方法求得的活化能数据平行性好.测定了标题化合物的感度性质,结果表明标题化合物具有一定的摩擦感度.A novel energetic coordination complex of [Co（AZT）2（H2O）4]（HTNR）2·4H2O（AZT = 3-azido-1,2,4-triazole,TNR=2,4,6-trinitro resorcinol） was prepared and characterized by elemental analysis and FT-IR spectroscopy.Single crystals of [Co（AZT）2（H2O）4]（HTNR）2·4H2O were obtained through slow evaporation of a saturated water solution.The molecular structure was determined by X-ray single crystal diffraction.The crystal belongs to the triclinic system with a P1 space group with crystal parameters of a=7.1824 ,b=10.1812 ,c=13.115 ,α=98.046°,β=105.367°,γ=104.103°,V=875.2 3,Z=1.The thermal decomposition mechanism of [Co（AZT）2（H2O）4]（HTNR）2·4H2O was predicted based on differential scanning calorimetry（DSC） and thermo-gravimetry-derivative thermo-gravimetry（TG-DTG） analyses.The kinetic parameters of the exothermic process of the compound were studied by Kissinger＇s,Starink＇s and Ozawa-Doyle＇s methods,with the apparent activation energy being 124.53,124.82 and 125.55 kJ·mol-1,respectively.Sensitivity tests reveal that the title complex has good friction sensitivity.
