摘要

A tetralithio salt (1) derived by treating 1,4-bis(trimethylsilyl)- cyclooctatriene with ~nBuLi serves as the first structural evidence for a multi-alkali metallocene. Single-crystal XRD confirms two Li ~+ each asymmetrically bind to η ~3 and η ~4 between two COT′′ rings and two Li ~+ terminally bind to η ~3. Solid-state NMR studies confirm the presence of two distinct lithium ion sites while the solution NMR studies suggest the formation of an (COT′′ dianion) ion-pair in solution. Further treating of the tetralithio salt with NaCl leads to linear sodium polymeric chains. Therefore, simply changing the ionic radius changes the molecular structure.
