Trimetallic FePd2 and FePt2 4-ferrocenyl-NCN pincer complexes

The synthesis and characterization of ferrocene-bridged NCN pincer complexes of structural type Fe(η5-C5H4-4-NCN-1-MX)2 (NCN = [C6H2(CH2NMe2)2-2,6]−; X = Cl, I; M = Pd, Pt) is described. Electrochemical measurements show a reversible oxidation of the ferrocene moiety and a dependency of the Fe(II)/Fe(III) potentials towards the presence of the M-halide moieties. The structure in the solid state of one (FePd2) species (6, MX = PdI) is reported as well.
