Abstract:	A new macrocyclic heterodinuclear Fe^IIICo^III 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 E^o ̄ is −0.229V (versus s.c.e) and α=0.877. The average electron transfer rate constant k^o′ is 3.21×10^-3 cm s^-1.
