Iron complexes redox behaviour

The redox behaviour of cobalt complexes is fairly similar to that of iron... 

Review work for future updates of our data base should focus on iron compounds and complexes. The iron system is thought to be of crucial importance for characterizing the redox behaviour of radioactive waste repositories. Preliminary applications have indicated that the lack of data for the iron system is a source of major uncertainties associated with the definition of an oxidation potential. Hence, there is little use in developing sophisticated redox models for radionuclides as long as the dominant redox processes in a repository are poorly known. 

In the solid state, iron complexes can display interesting internal redox behaviour as a result of applying high pressure.54 Reduction of iron(III) to iron(II) on the application of pressure is well documented and is usually monitored by Mossbauer or optical spectroscopy. For instance, conversion to iron(II) in [Fe(acac)3] proceeds continuously with pressure over the range above 30kbar,... 

Iron-sulfur chemistry has developed over recent years to become a very rich area. A feature of many complexes is their redox behaviour, with more than one oxidation state being important. This... 

The redox properties of macrobicyclic iron(II) mono- and binuclear oximehydrazonates and a-dioximates formed by capping with antimony(V) and germanium(IV) triorganyles were studied by cyclic voltammetry [73, 74]. The electrochemical behaviour of these compounds is similar to that of analogous boron- and tin-capped clathrochelates. Oxidation of all mononuclear complexes involves a one-electron process, assigned to the oxidation of encapsulated iron(II) ion to iron(III) ion. This process is electrochemically... 

The redox properties of complexes of the cobalt triade with [2 ]cyclophanes [78] as well as iron [180] were also examined and show a similar behaviour as...
