Decamethylmetallocenes Cp*2M (M= Mn, Fe, Co, Ni) are oxidized to the respective dications by application of powerful oxidants (e.g. SbF5, AsF5) in SO2 or anhydrous HF. The choice of oxidants and the crystal structures of the products are discussed. Special emphasis is put on the characterization of the room-temperature stable Cp*2Fe2+ dication. While the crystal structure of the corresponding SbF6- salt displays a slightly bent structure, the Cp* rings are parallel in the Sb2F11- salt. Addionally, the results of SQUID and Mößbauer measurements are presented.
