Redox-induced fluoride ligand dissociation stabilized by intramolecular hydrogen bonding

Abstract

Chemical reduction of a tripodal Cu(II)–F complex containing pendent hydroxyl groups results in the partial dissociation of a F⁻ ligand from Cu. The resulting Cu(I) complex is characterized as containing an outer sphere F⁻ anion ‘captured’ by hydrogen bonds. The pendent hydroxyl groups were found to be crucial for reductive stability.
