Attempted sublimation of the known chromium(II) iodo complex [4CpCr(µ‐I)]2 resulted in a redox reaction with formation of the chromium(III) iodo dimer [4CpCrI(µ‐I)]2, whose tri(tert‐butyl)cyclopentadienyl derivative [Cp′′′CrI(µ‐I)]2 (4) could also be prepared by oxidation of [Cp′′′Cr(µ‐I)]2 with iodine.
