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.
