Abstract:

The isotropic shifts of the 11B and 13C nuclear resonances in paramagnetic metallocarboranes of the type C5H5MC2BnHn2 and MC2BnHn22 where M CrIII, FeIII, NiIII, CoIII, and n 9,8,7,6, were evaluated. Electron spin resonance data are also discussed. The mode of electron delocalization is primarily ligand to metal charge transfer, except for icosahedral CoII, where it is metal to ligand. The extent of delocalization in metallocarboranes is minimal and is primarily localized on the metal bonding face. The results of this study are compared to available data and theories related to paramagnetic metallocenes. Modified author abstract
