Complete assignments of chemical shifts in the H-1 and C-13 NMR spectra for a contiguous series of [(eta(5)-C6H7)Fe(eta(6)-MenC6H6-n)](+) and [(eta(5)-C5H5)Fe(eta(6)-MenC6H6-n)](+) cations (where n = 0-6) are reported. The spectra revealed a straightforward linear correlation between delta(H-1) or delta(C-13) 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 interligand substituent effect and its transmission onto the second (Chd or Cp) ring via the Fe-II center.
