โœฆ Synopsis


Organometallic compounds of rhenium occur in high and low oxidation states. These complexes are characterized by a variety of excited states including ligand field (LF), ligand-to-metal charge transfer (LMCT), metal-to-ligand charge transfer (MLCT), ligand-toligand charge transfer (LLCT), metal-to-metal charge transfer (MMCT), and intraligand (IL) excited states. The nature of the lowest-energy excited state can be tuned by the choice of appropriate ligands and metal oxidation states. This diversity is illustrated by selected examples of organometallics of Re(VII) and Re(I). Our account emphasizes spectral (absorption and emission) as well as photochemical properties.
