The first ReI organometallic complex with an organoimido-polyoxometalate ligand

Abstract

The spectroscopic, electrochemical and photophysical properties of the first Re^I organometallic organoimido-polyoxometalate complex [n-Bu₄N][Mo₆O₁₈NC₆H₄-CH₂-N₃C₂H₂-Re-phen(CO)₃] compared with all fragments are reported. The UV–Vis spectra are analysed using experimental and theoretical tools. In contrast to the reported studies in the literature, our results show that a new more intense band is present in the spectra of the hybrid ligand obscuring the intra-polyanion charge transfer. The electrochemical results show that the strong acceptor character of the polyoxometalate fragment is quenched by the condensation of the phenyl-triazole molecule.
