非桥基配体对配合物的电子转移反应的影响——Cis-[Co(en)_2Cl_2]^+和Cis-[Co(en)_2(OH)_2Cl]^(2+)与Fe(Ⅱ)间电子转移反应

THE EFFECT OF NONBRIDGING LIGANDS ON THE ELECTRON-TRANSFER REACTIONS OF COMPLEXES --The electron transfer reaction between Cis-[Co(en)_2Cl_2]^+ or cis-[Co(en)_2(OH_2)Cl]^(2+) and Iron(Ⅱ)

在成桥活化配合物反应机理基础上,Ogarl,P.Benson等人,根据中心离子的结构和成桥基配体的性质,用配位场理论,研究报导了水中配合物间电子转移反应的动力学行为。本文,在混合溶剂中配合物间电子转移反应机理研究的基础上,探索了非桥基配体Cl-和H2O,对H2O、H2O—McOH、H2O—DMF等溶剂中Cis-[Co（cn）2Cl2]+和Cis-[Co（cn）2（OH2）Cl]2+和Fe（Ⅱ）间电子转移反应的影响。实验发现:相同条件下。

Investigations have been made in the effect of nonbridging ligands on the electron transfer reactions between Cis-[Co(en)_2Cl_2]^+ or Cis-[Co(en)_2(OH_2)Cl]^(2+) and iron(Ⅱ), and the effect of nonbridging ligand (Cl^- and H_2O) on the apparent rate constants of the reactions have also been expounded using spectrochemical series of ligand and crystal field stabilization energy.
