Half-Sandwich Zirconium and Hafnium Amidoborane Complexes: Precursors of Hydride Derivatives.

ABSTRACT: Half-sandwich zirconium(IV) and hafnium(IV) complexes with amidoborane and hydride ligands have been isolated in the stoichiometric reactions of mono(pentamethylcyclopentadienyl)metal alkyl and amido derivatives with the amine-boranes NHR₂BH₃ (R₂ = H₂, Me₂, HtBu). Treatment of the tris(trimethylsilylmethyl) complexes [M(η⁵-C₅Me₅)(CH₂SiMe₃)₃] with NH₃BH₃ (3 equiv) gives the seven-coordinate species [M(η⁵-C₅Me₅)(NH₂BH₃)₃] (M = Zr (1), Hf (2)) with three κ²N,H-NH₂BH₃ ligands. The tris(neophyl) [M(η⁵-C₅Me
