Abstract
Platinum-cluster-to-iron charge transfer complex, FcC≡C[Pt6]C≡CFc [1; Fc = (η-C5H5)Fe(η-C5H4), [Pt6] = [Pt6(μ-PBut2)4(CO)4]2+] was prepd. in good yields by the CuI-catalyzed coupling of two equiv. of ethynylferrocene with the hexanuclear cluster [Pt6(μ-PtBu2)4(CO)4Cl2]. Electrochem. and spectroelectrochem. data of 1 show photoelectrochem. triggered electron transfer from the {Pt6} core to the peripheral ferrocenyl subunits.File in questo prodotto:
