Abstract

[Cp₂Ln(μ-OH)(THF)]₂ react with 2 equiv of CyNCNCy (Cy = cyclohexyl) to form [Cp₂Ln(μ-OC(NHCy)NCy)]₂ (Ln = Er (1-Er), Y (1-Y)), while treatment of [Cp₂Ln(μ-OH)] ₂(μ₃-O)LnCp(THF) with CyNCNCy affords the addition/rearrangement products [Cp₂Ln(μ₃-O)(μ- OC(NHCy)NCy)LnCp]₂ (Ln = Yb (3-Yb), Er (3-Er)). Compounds [(Cp ₂Ln)₂(μ₃-CO₃)(THF)]₂ (Ln = Yb (4-Yb), Er (4-Er)) can be obtained by treatment of [Cp ₂Ln(μ-OH)(THF)]₂ with CO₂ immediately followed by the reaction with the corresponding Cp₃Ln. Complexes 1-4 were characterized by elemental analysis, spectroscopic properties and X-ray single crystal diffraction analysis.
