Abstract

The triple-decker cations trans-[(Cp*Sn)2(μ-η5:η5-Cp*)]+ and trans-[(Cp*Pb)2(μ-η5:η5-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.
