摘要：
Reaction of the strong Lewis acid B(C6F5)(3) with [M{N(SiMe3)(2)}(3)Me] (M = Zr or Hf) gave the compounds [M{N(SiMe3)(2)}(3)][MeB(C6F5)(3)]. Crystallographic analyses of these compounds revealed the formation of multicentre bonds between the SiCH3 units of the amide ligands and the otherwise electron-deficient metal centre. The new tris(amide) complexes [M{N(Ph)SiMe3}(3)Cl] and [M{N(Ph)SiMe3}(3)Me] (M = Zr or Hf) have also been synthesized.
