摘要
在FeCl2.4H2O和CoCl2.6H2O存在下，由2,6-二甲酰吡啶n -氧化物与1,3-二氨基丙烷缩合制备了一种新的大环杂二核feiicoiii配合物，并将其配方为FeCoLCl6.C2H5OH。通过元素分析、红外光谱和Mössbauer光谱对8H2O进行了表征，并在超微盘铂电极上进行了电化学研究。结果表明，电极反应可以看作是一个几乎可逆的转移过程。扩散系数为1.93×10-6 m2 s-1, Eo为- 0.229V(相对于s.c.e)， α=0.877。平均电子转移速率常数ko '为3.21×10-3 cm s-1。
Preparation and electrochemical behavior of a macrocyclic heterodinuclear FeIIICoIII complex
A new macrocyclic heterodinuclear FeIIICoIII complex, prepared by the condensation of 2,6-diformylpyridine N-oxide with 1,3-diaminopropane in the presence of FeCl2.4H2O and CoCl2.6H2O, and formulated as FeCoLCl6.C2H5OH.8H2O, was characterized by elemental analyses, IR and Mössbauer spectra and investigated electrochemically on an ultramicrodisk platinum electrode. The results show that the electrode reaction can be thought as a nearly reversible transfer process. The diffusion coefficient is 1.93×10-6 m2 s-1 and Eo ̄ is −0.229V (versus s.c.e) and α=0.877. The average electron transfer rate constant ko′ is 3.21×10-3 cm s-1.
