The electrochemical oxidation of ferricyanide, [Fe-III(CN)(6)](3-), was investigated and the oxidation product was characterized using in-situ FTIR and XAS spectroelectrochemistry methods. The oxidation process is proposed to involve a tentative Fe(IV) intermediate before forming a stable product in acetonitrile. The speciation of the oxidation product was confirmed by DFT calculations, which showed good agreement with experimental data.
We report the electrochemical oxidation of ferricyanide, [Fe-III(CN)(6)](3-) and characterised the oxidation product by in-situ FTIR and XAS spectroelectrochemistry methods. Oxidation of [Fe-III(CN)(6)](3-) is proposed to proceed via a tentative Fe(IV) intermediate that undergoes reduction elimination to give cis-[Fe-III(CN)(4)(CH3CN)(2)](1-) as stable product in acetonitrile. Speciation of the oxidation product by DFT calculations is underpinned by good agreement to experimental data.
