Treatment of MAr2 [Ar- = C?6H3(NMe2)2-2,6 and M = Ge (1) or Sn (2)] with silicon tetrachloride, or 2 with SiCl3Me, under mild conditions in diethyl ether afforded in good yields the appropriate silylgermane or -stannane M(Ar)2Cl(SiCl3) [M = Ge (3), Sn (4)] and Sn(Ar)2Cl(SiCl2Me) (5). The X-ray structures of 3 and 5 show that while in 3 there is no very close Ge?N contact (the molecule having germanium in a distorted tetrahedral environment), 5 has a distorted pyramidal structure around the tin atom, with a Cl and a N atom in apical sites. Solutions of 3 and 4 in C6D6 showed the former to be stable, while the latter slowly decomposed, yielding β-tin and Sn(Ar)2Cl2 among the products; solutions of 5 showed the presence of the equilibrium 2 + SiCl3Me ? 5, and in CDCl3the mixture afforded Sn(Ar)2Cl(CDCl2).
