Abstract
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.
