Abstract

The synthesis of the first isolable geminal 1,1-dilithiostannane is reported. In the solid state, the novel 1,1-dilithiostannane has three different structural motifs, depending on the reaction conditions used for its synthesis: (1) an unsolvated co-aggregate consisting of two 1,1-dilithiostannane molecules and two silyllithium molecules, {[(tBu₂MeSi)₂SnLi₂]₂ ⋅ [tBu₂MeSiLi]₂}; (2) a solvated trimeric stannyllithium dianion {[(tBu₂MeSi)₂Sn]₃Li₄}²⁻ associated with two fully dissociated THF-solvated Li⁺ cations; (3) a THF-solvated contact-ion pair dimer of 1,1-dilithiostannane, [(tBu₂MeSi)₂SnLi₂]₂ ⋅ (THF)₄.
