Optical metal to ligand charge-transfer (MLCT) transitions play an important role in the photophysics and photochemistry of transition-metal complexes. This electronic transition is an intramolecular (inner-sphere) process. It involves the promotion of a d electron of the metal to an empty orbital of a ligand coordinated to this metal. MLCT transitions occur at low energies if the metal is a reducing one and the ligand has available empty low-energy orbitals. Typical examples are the complexes Ru(bpy)3S (bpy = 2,2'-bipyridyl) and M(CN)6U (M = Fe, Ru, Os). In the latter case MLCT excitation is associated with the generation of solvated electrons. They report here on intermolecular (outer-sphere) MLCT transitions and the photochemistry following this type of CT excitation. In this case the optical transition involves the promotion of an electron from the metal of one complex to the ligand of another complex. The ion pairs Rh(bpy)3S M(CN)6U with M = Fe, Ru, Os were selected for this study.
