One, two or even three coordinated phenoxyl radical ligands are present in the mono-, di- and trications, formed by stepwise oxidation of complexes of the type shown on the right. The starting materials are very stable mononuclear neutral complexes of gallium(III), scandium(III) or iron(III) with hexadentate macrocyclic ligands based on a 1,4,7-tris-phenolato-l,4,7-triazacyclononane core structure.
