摘　　要：Recent decades have witnessed a rapid development of the lanthanide silicon chemistry.In this research,by reacting[(THF)_(3)LisiPh_(3)]with Cp_(3)Ln(Ⅰ)(THF)(Ln(I)=Sm(Ⅰ),Tb(Ⅱ),Dy(Ⅰ),Yb(Ⅰ)or Cp_(2)Lu(Ⅱ)CI(THF),a series of middle-and heavy-lanthanocene monosilyl/disilyl ate-complexes([(DME)_(3)Lil[Cp_(3)Ln(Ⅱ)SiPh_(3)]and[(DME)_(3)Li[Cp_(2)Lu(Ⅱ)(SiPh_(3))_(2)])were synthesized.The structures of the obtained lanthanocene monosilyl/disilyl ate-complexes were determined by single crystal X-ray diffraction.Together with the previously reported[(DME)_(3)Li[Cp_(3)La(Ⅱ)SiPh_(3)]and[(DME);Lil[Cp_(3)Ce(Ⅱ)SiPha],a complex group comprising silyl light-,middle-and heavy-lanthanocene with identical core coordination pattern are presented.
