[{(tBu2Me)2Si}3Li4]2−: An Aggregated Dianion of a 1,1-Dilithiosilane with a Unique Structural Motif

An anionic dilithium compound: The dianion [(R2Si)3Li4]2− (R=tBu2MeSi) as salt 2 was synthesized as the first of its kind by dissolving 1 in THF. The structure of 2 was solved by X‐ray crystallography and studied by solid‐state and solution NMR spectroscopy. Compound 2 reacts as a dilithiosilane....
