Abstract
A route for the synthesis of coordinatively dissymmetrical iron(II) polypyridine complexes [Fe(L)2L′]2+ (L and L′ are two different 2,2′-bipyridine derivatives) is described. The procedure is based on the use of the precursor [Fe(L)2(CH3CN)2]2+ (L=2,2′-bipyridine), which can be easily prepared by electrochemical or chemical reduction of the μ-oxo diaqua diiron(III) complex [Fe2O(bpy)4(H2O)2]4+ in acidic CH3CN solution. In addition, it is shown that this procedure can be applied with success to the synthesis of covalently linked heterodinuclear complexes containing, for instance, Fe(bpy)32+ and Ru(bpy)32+ moieties. The electrochemical behaviour of all these new complexes is reported.Keywords
