摘要：
The ate complexes [M{C(SiMe3)(3)}(mu-SBu)(2)Li(THF)(2)], M = Ge or Sn, have been made from M(SBu)(2) and LiC(SiMe3)(3) in tetrahydrofuran and their crystal structures determined. The LiS2M rings are. folded at the S...S axis, the ring in the tin compound more so than that in the germanium derivative. The latter has a conformation very like the ring in [(Me3Si)(3)CAl(SMe)(mu-SMe)(2)Li(THF)(2)]. NMR measurements show that the LiS2M rings are preserved in toluene solution, but the Li-S bonds in the tin compound are transiently broken in THF.
