N2 - It was fortunate that the first extended branched polysilyl anion (Me3SiMe2Si)3Si- could be crystallographically characterized in two forms - as the THF complex 1 and as the dimer 2. Comparison with the analogous (Me3Si)3SiLi systems 3 and 4 shows that β-Me3Si substitution and complexation by THF elongate the Si-Li distance by 0.09-0.14 Å and 0.04-0.07 Å, respectively.
