Abstract: High Resolution Image Download MS PowerPoint Slide The analysis of intervalence charge transfer (IVCT) in mixed-valence compounds can help understand electron transfer processes that are important in diverse applications such as molecular electronics and artificial photosynthesis. While mixed-valence complexes of the lanthanides are more difficult to access than their transition metal analogues, they have shown IVCT phenomena derived from Robin–Day Class II localized valency or even electronic transitions due to d – d metal–metal bonding. In contrast, we report here the synthesis, characterization, and computational analysis of a rare, Robin-Day Class III, singly reduced dinuclear Yb complex, which is best viewed as having delocalized oxidation states. In this case, no metal–metal bonding occurs and, for the first time, IVCT in a Robin–Day Class III complex resulting from f – f transitions is observed.
