Complete assignments of chemical shifts in the ¹H and ¹³C NMR spectra for a contiguous series of [(畏⁵-C₆H₇)Fe(畏⁶-Me_nC₆H_6鈥?i>n)]⁺ and [(畏⁵-C₅H₅)Fe(畏⁶-Me_nC₆H_6鈥?i>n)]⁺ cations (where n = 0鈥?) are reported. The spectra revealed a straightforward linear correlation between 未(¹H) or 未(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 interligand substituent effect and its transmission onto the second (Chd or Cp) ring via the Fe^II center.
