Abstract
The EPR, 1H and 13C NMR spectra of methylferricinium hexafluorophosphates, [(MenCp)2Fe]PF6, n = 0-5, have been recorded. HFS constants have been estimated for all the ligand atoms. The general pattern of the spin density distribution is shown to depend on the superposition of the various mechanisms of spin delocalization. For the majority of the cations the determining factors has been found to be represented by spin polarization over the π-skeleton.Keywords
