Remarkable solvent dependence of the apparent peak-to-peak linewidth (ΔHpp) has been observed for the rhombic type of e.s.r. spectra of the high-spin FeIII(edta) (edta = ethylenediaminetetra-acetate) and FeIII(hedta) hedt

The oxidation of FeII(L) complexes by molecular oxygen is significantly enhanced by the presence of a chelating ligand L. The kinetics of this reaction was studied for L = ethylenediaminetetraacetate, N-(hydroxyethyl)ethylenediaminetriacetate, and diethylenetriaminepentaacetate as a function of [FeII(L)], [O2], pH, temperature, and pressure. All the observed kinetic relationships can be accounted for in terms of a mechanism in which O2 rapidly reacts with FeII(L) to produce FeII(L)O2, followed by three parallel reaction steps. These include spontaneous and acid-catalyzed electron transfer, as well as a reaction with FeII(L) to produce (L)FeIII-O22--FeIII(L). The results are discussed in reference to the available literature data for these and related oxidation processes.
