Abstract

Reactions between LiC(SiMe₃)₂(SiMe₂ C₅H₄N-2), 1, and the halides GeCl₂·dioxane, SnCl₂, and PbCl₂ gave the isostructural compounds MCl{C(SiMe₃)₂ (SiMe₂C₅H₄N-2)} (M = Ge, 2; Sn, 3; or Pb, 4) which contain three-coordinate M. Treatment of the tin derivative 3 with MeI gave the oxidative addition product SnMeClI{C(SiMe₃)₂ (SiMe₂C₅H₄N-2)}, 5, and this reacted with AgOCOCF₃ or AgOSO₂C₆H₄Me-4 to give, respectively, the compounds SnMeX₂-{C(SiMe₃)₂ (SiMe₂C₅H₄N-2)} with X = OCOCF₃, 6, or OSO₂C₆H₄Me-4, 7. Despite the presence of the bulky C(SiMe₃)₂(SiMe₂C₅H₄ N-2) ligand, the Sn atom in the solid state structures of 6 and 7 is five-coordinate, and multinuclear NMR studies show that five-coordinate species are present also in THF solutions of 5, 6, and 7.
