Synthesis of the First Isolable Geminal 1,1‐Dilithiostannane and Its Intriguing Structural Diversity
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, {[(tBu<sub>2</sub>MeSi)<sub>2</sub>SnLi<sub>2</sub>]<sub>2</sub> ⋅ [tBu<sub>2</sub>MeSiLi]<sub>2</sub>}; (2) a solvated trimeric stannyllithium dianion {[(tBu<sub>2</sub>MeSi)<sub>2</sub>Sn]<sub>3</sub>Li<sub>4</sub>}<sup>2-</sup> associated with two fully dissociated THF-solvated Li<sup>+</sup> cations; (3) a THF-solvated contact-ion pair dimer of 1,1-dilithiostannane, [(tBu<sub>2</sub>MeSi)<sub>2</sub>SnLi<sub>2</sub>]<sub>2</sub> ⋅ (THF)<sub>4</sub>.
