Abstract
Half-wave potentials,E1/2, of Fe(ligand)63+/2+, as ClO4− salt, [ligand=N,N-dimethylformamide (dmf), acetamide (aa), N,N-dimethylacetamide (dma), trimethylphosphate (tmp), dimethylsulfoxide (dmso), and acetonitrile (MeCN) are given. A linear correlation betweenE1/2 and Gutmann's donor numbers of the ligands, a parameter which expresses quantitatively the Lewis donor properties towards hard acceptors, was found. Ligand replacement on Fe(ligand)63+ in acetonitrile-d3 was studied by means of1H-NMR spectroscopy at 20°C. An average number of ligands coordinated to Fe3+,ncoord, is given.ncoord increases with the ligand's donor strength; i.e.tmp<dmf<dmso.
