摘　　要：利用4-氨基-1,2,4-三唑（4-ATz）与二水氯化铜合成了标题化合物（C2N4H4）2CuCl2.H2O,采用元素分析和红外光谱分析对配合物进行了结构表征,用DSC和TG-DTG研究了配合物的热行为及主放热分解阶段的动力学。结果表明,金属离子与配体的化学计量比为12。配合物的主要分解阶段由机理函数f（α）=32（1-α）[-ln（1-α）]1/3控制,反应速率方程为：dα/dt=1021.83×3/2（1-α）[-ln（1-α）]1/3×exp（-2.75×10~4/T）。Cu（4-ATz）2Cl2·H2O was synthesized with 4-amino-1,2,4-triazole（4-ATz） and copper chloride dihydrate,and was characterized by elemental analysis,IR and melting point determination.The thermal behaviors and nonisothermal demposition reaction kinetics of the complex were studied by differential scanning calorimetry（DSC） and thermogravimetry and derivative thermogravimetry（TG-DTG） techniques.The results show that the mole ratio of metal to ligand is 12.The reaction mechanism of the main exothermic decomposition process of the complex is classified as chemical reaction and f（α）=3/2（1-α）[-ln（1-α）]1/3,and the kinetic equation is obtained as：dα/dt=1021.83×3/2（1-α）[-ln（1-α）]1/3×exp（-2.75×104/T）.
