The autoxidation reaction of the Fe2+/ethylenediaminetetraacetic acid system has been studied in solution phase at neutral pH and in solid state using Mössbauer spectroscopy. It was found that despite the proposed reaction pathway consisting of several reaction steps under similar circumstances, no intermediate species could be seen in the Mössbauer spectra and instead of the formation of the well-known [FeIII(EDTA) (H2O)]- species, the direct formation of its dimeric form was observed.
