Description
Summary:The He(II) spectra of the unsubstituted metallocenes {M(η-C 5H 5) 2}, M  V, Cr, Mn, Fe, Co, Ni and Ru, and of {Mn(η-C 5H 4Me) 2} are reported; both He(I) and He(II) spectra of some decamethylmetallocenes {M(η-C 5Me 5) 2}, where M  Mg, V, Cr, Mn, Fe, Co and Ni, are also given. Intensity changes between the He(I) and He(II) spectra are shown to provide a reliable guide to band assignment. A ligand field treatment of the decamethylmanganocene cation, including limited configuration interaction, gives values for Δ 2, B and C; these values are also in good agreement with the photoelectron spectra of {M(η-C 5Me 5) 2} where M  V, Cr and Fe. Overlap between the ligand and metal “ d” band structures prevents complete assignment in the cases of Co and Ni.
