series of [(η5-C6H7)Fe(η6-MenC6H6–n)]+ and [(η5-C5H5)Fe(η6-MenC6H6–n)]+ cations (where n = 0–6) are reported. The spectra revealed a straightforward linear correlation between δ(1H) or δ(13C) parameters of the cyclohexadienyl (Chd) and cyclopentadienyl (Cp) rings and the number of arene methyl substituents (n), which is consistent with an additive character of the interligandsubstituent effect and
