摘要：
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.
