Stack by Stack: From the Free Cyclopentadienylgermanium Cation Via Heterobimetallic Main-Group Sandwiches to Main-Group Sandwich Coordination Polymers.

ABSTRACT: Heterobimetallic cationic sandwich complexes [M(μ-Cp)M'Cp]⁺ of group 13 (M=Ga, In) and group 14 (M'=Ge, Sn) elements have been prepared as [WCA]^- salts (WCA=Al(OR^F )₄ ; OR^F =OC(CF₃ )₃ ). Their molecular structures include free apical gallium or indium atoms. The sandwich complexes were formed in the reactions of [M(HMB)]⁺ [WCA]^- (HMB=C₆ Me₆ ) with the free metallocenes [M'Cp₂ ]. Their structures are related to known stannocene and stannocenium salts; the unprecedented germanium analogues, namely the free germanocenium cation [GeCp]⁺ and the corresponding triple-decker complex cation [CpGe(μ-Cp)GeCp]⁺ , are described herein.
