Abstract: Electrochemical and spectro-electrochemical properties of n-oxo-tetrabromophthalocyaninato iron ([TBPcFe]₂O) were studied.The experimental results showed that u-oxo-tetrabromoph-thalocyaninato iron undergoes three one-electron redox reactions,the half-wave potentials (E_1/2) of which are 0.06V,-0.75V and -1.33V (Hg₂Cl₂/Hg reference),corresponding to Fe³⁺/ Fe²⁺,Fe²⁺/Fe⁺ and TBPc^2-/TBPc^3- respectively.The typical spectra of the corresponding; complexes were also observed in the spectro-electrochemical studies.

Key words: tetrabromophthalocyaninato iron, spectro-electrochemical method
