在水溶液中采用NiCl2.6H2O与吡啶-2,6-二甲酸(H2PDC)和1,10-菲啰啉(phen)反应生成了配合物[Ni(phen)2(H2O)2][Ni(PDC)2].7H2O.通过元素分析和单晶X射线衍射对生成的配合物进行了表征,采用微热量计测定了液相反应的焓变。结果表明:反应生成的配合物属于三斜晶系,空间群为P1-.根据实验数据计算出了标题配合物生成反应的热动力学参数(活化焓、活化熵和活化自由能)、反应速率常数和动力学参数(表观自由能、指前因子和反应级数)。在所研究的温度范围内,配合物的生成反应为放热反应,反应温度越高,反应速率越快。
The complex [Ni (phen) 2 (H2O) 2] [Ni (PDC) was synthesized by the reaction of NiCl2.6H2O with pyridine-2,6-dicarboxylic acid (H2PDC) and 1,10-phenanthroline (phen) ) 2] .7H2O. The complexes were characterized by elemental analysis and single crystal X-ray diffraction. The enthalpy change of the liquid-phase reaction was determined by microcalorimeter. The results show that the complex formed by the reaction belongs to the triclinic system and the space group is P1-. According to the experimental data, the thermokinetic parameters (enthalpy of activation, activation entropy and activation free energy) of the title complex were calculated. The reaction rate Constants and kinetic parameters (apparent free energy, pre-exponential factor and reaction order). In the temperature range studied, the complex formation reaction is exothermic reaction, the reaction temperature is higher, the reaction rate is faster.
