Comparison of group 4 and thorium M(IV) substituted cyclopentadienyl silanide complexes.

ABSTRACT: We report the synthesis and characterisation of a series of M(IV) substituted cyclopentadienyl hypersilanide complexes of the general formula [M(Cp^R)₂{Si(SiMe₃)₃}(X)] (M = Hf, Th; Cp^R = Cp', {C₅H₄(SiMe₃)} or Cp'', {C₅H₃(SiMe₃)₂-1,3}; X = Cl, C₃H₅). The separate salt metathesis reactions of [M(Cp^R)₂(Cl)₂] (M = Zr or Hf, Cp^R = Cp'; M = Hf or Th, Cp^R = Cp'') with equimolar K{Si(SiMe₃)₃} gave the respective mono-silanide complexes [M(Cp')₂{Si(SiMe₃)₃}(Cl)] (M = Zr, 1; Hf, 2), [Hf(Cp'')(Cp'){Si(SiMe₃)₃}(Cl)] (3) a
