Electronic and electrochemical properties of cationic complexes [Fe(R-Sal)2Trien]+ in solution: Evidence of formation of phenoxyl radicals upon oxidation

Investigations on the electronic and the electrochemical properties of four ferric complexes based on substituted hexadentate Schiff base ligands were carried out. The occurrence of spin equilibria in solution was demonstrated and the formation of phenoxyl radicals was characterised in this family of ferric complexes for the first time.
