  Synthesis and Structure of Yttrium and Lanthanide Bis(phosphinimino)methanides

  摘要：

  Reaction of K{CH(PPh2NSiMe3)(2)} (1) with anhydrous yttrium or lanthanide trichlorides leads to [{CH(PPh2NSiMe3)(2)}LnCl(2)](2) (Ln = Y (2a), Sm (2b), Er (2c), Dy (2d), Yb (2e), Lu (2f)). The single-crystal X-ray structures of these complexes show that the methine carbon is bound to the lanthanide atom. This is supported by DFT calculations, which show a comparable interaction. Due to the similar ion radii of the lanthanides, the single-crystal X-ray structures of 2a-f are isostructural. Further reaction of 2 with KNPh2 afforded [{CH(PPh2NSiMe3)(2)}Ln(NPh2)(2)] (Ln = Y (3a), Sm (3b)). These complexes show in comparison to 2 a similar coordination behavior of the {CH(PPh2NSiMe3)(2)}(-) ligand in the solid state and in solution.
