采用溶液法合成了分子式为[Cu2(phen)2(OH)2(H2O)2][Cu2(phen)2(OH)2Cl2]Cl2.6H2O的配合物。通过元素分析、红外光谱、紫外光谱和X-射线单晶衍射对配合物进行了表征;此外,还对该配合物进行了非等温热分解动力学研究。研究表明,配合物中有两组双核配位单元,分别为[Cu2(phen)2(OH)2(H2O)2]2+和[Cu2(phen)2(OH)2Cl2];两个配位单元的中心原子铜均为五配位的,具有扭曲的四方锥结构,配合物通过氢键作用形成超分子结构。此配合物的热分解反应是分两步进行的,第一步反应的动力学方程为dαdT=Aφ.exp-E()R T3/2[(1-α)43(1-α)-13-]1-1,活化能E=151.8kJ/mol,指前因子lgA=16.9435;第二步反应的动力学方程为dαdT=Aφ.exp-E()R T32[(1-α)43(1-α)-13-]1-1,活化能E=201.5kJ/mol,指前因子lgA=7.5447。
The complex of [Cu2 (phen) 2 (OH) 2 (H2O) 2] [Cu2 (phen) 2 (OH) 2Cl2] Cl2.6H2O was synthesized by solution method. The complex was characterized by elemental analysis, IR, UV and X-ray single crystal diffraction. In addition, the non-isothermal decomposition kinetics of the complex was also studied. The results show that there are two groups of dinuclear coordination units in the complex, which are [Cu2 (phen) 2 (OH) 2 (H2O) 2] 2+ and [Cu2 (phen) The central copper atoms of the unit are all five-coordinated and have a distorted tetragonal pyramidal structure. The complex forms a supramolecular structure through hydrogen bonding. The thermal decomposition reaction of the complex is carried out in two steps. The kinetic equation of the first reaction is dαdT = Aφ.exp-E () R T3 / 2 [(1-α) 43 (1-α) -13 -] 1-1, the activation energy E = 151.8 kJ / mol and the pre-exponential factor lgA = 16.9435. The kinetic equation for the second reaction is dαdT = Aφ.exp-E () R T32 [ 1-α) -13-] 1-1, activation energy E = 201.5kJ / mol, pre-exponential factor lgA = 7.5447.
