The ate complexes [MC(SiMe3)3}(μ-SBu)2Li(THF)2], M = Ge or Sn, have been made from M(SBu)2 and LiC(SiMe3)3 in tetrahydrofuran and their crystalstructures 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)3CAl(SMe)(μ-SMe)2Li(THF)2]. NMR measurements show that
