Valence tautomerism involves the coexistence of redox isomers with different charge and spin density distributions, induced by intramolecular electron transfer and stimuli like light, X-ray, or temperature variations. This study proposes chromium half-sandwich complexes as alternatives, highlighting their advantages, including easily adjustable oxidation potentials, CO ligands for infrared spectroscopy, and EPR activity at a more convenient temperature (77 K) compared to ferrocene complexes.
