[Co(NH35)Cl]Cl2、[Co(NH3)5NO2]Cl2与[Co(NH3)5ONO]Cl2是以CoCl2为原料合成的钴的三种配合物.本文首先合成了这三种钴的配合物,然后对钴的这三种配合物的性质进行了研究,测定了[Co(NH3)5Cl]Cl2的水合速率常数和活化能.实验结果表明,随着温度的升高,化合物[Co(NH3)5ONOC]l2的结构发生了转变;[Co(NH3)5Cl]Cl2水合反应速率常数在60℃和80℃时分别为0.0494min-1和0.0739min-1.活化能为21.257kJ/mol.

[Co（NH3）5Cl] Cl2 ,[Co（NH3）5NO2] Cl2 and [Co（NH3）5ONO] Cl2 were synthesized from CoCl2 · 6H2O. These compounds were studied after synthesized in this paper. The characters of the three complexes were characterized and the hydration velocity constant of [ Co（NH3）5Cl]Cl2 and its activity energy were determined. The results show that the structure of the compound changed when it is heated at a certain temperature, and its constant of reactivity at 60 ℃ being 0. 0479 min^-1, 0. 074 min^-1 at 80 ℃, and the activity energy being 21. 257 kJ/mol.
