The triple-decker cations trans-[(Cp*Sn)2(μ- η5:η5-Cp*)]+ and frans-[(Cp*Pb)2(u-rf:rf-Cp*)]+ have been prepared and structurally characterized as their [B(C6F5)4]- salts from the reactions of [Cp*M][B(C6F5) 4] (M = Sn, Pb) with the appropriate decamethylmetallocene. Both triple-decker cations adopt a cisoid arrangement of terminal Cp* groups, whereas the two known triple-decker main-group anions possess a transoid arrangement of terminal Cp groups. The reason for this conformational difference has been probed on the basis of DFT calculations. The Royal Society of Chemistry 2005.
