Abstract

Novel self-assembled monolayers of a mixed-valent (μ3-oxo)triruthenium(II,III,III) complex containing a terminal CO ligand were constructed on Au(111) electrode surface and were characterized by cyclic voltammetry and in situ Fourier transform infrared reflection absorption spectroscopy (FT-IRRAS). A distinctive infrared v(CO) absorption band was observed at 1950 cm-1 for the original {Ru11-CO}Ru111Ru111 complex in an aqueous 0.1 M NaClO4 solution and it shifted to 2060 cm-1 upon one-electron oxidation of the Ru11 center.
