Formation of iron(VI) in ozonalysis of iron(III) in alkaline solution

Here we report the formation of iron in hexavalent state, View the MathML sourceFeVIO42- in ozonalysis of iron(III) in alkaline medium. The formation of tetrahedral View the MathML sourceFeVIO42- ion is confirmed by UV–Visible and Mössbauer spectroscopic techniques. The value of isomer shift, δ, of the tetra-oxy anion is consistent with known δ values for various salts of iron(VI) ion.
