The metallotropic η6 ⇌ η5 tautomeric equilibrium in anionic chromium tricarbonyl complexes of fluoradene, substituted fluorenes and indene has been studied. A criterion is proposed for determining the ion-pair type in η6-anions according to the E-band splitting in the ν(CO) region of their IR spectra. The influence of ligand structure and cation solvation on Keq. is discussed.
