Recent developments have helped to extend the repertoire of mixed‐valent ruthenium and osmium complexes beyond conventional systems. This extension has been achieved by using sophisticated ligands and by creating more variegated coordination patterns. The strategies employed include the use of multidentate ligands (which give rise to multinuclear and chelate complexes) and the use several redox active components (non‐innocent ligands and oxidation‐state ambivalence). The results offer enhanced chemical insight into metal–ligand electron‐transfer situations and suggest that mixed‐valent materials may eventually be exploited in molecular electronics and molecular computing.
