Synthesis and Structural Characterization of Novel Ytterbium(III) Complexes with both a μ‐Oxo Group and Bridged Indenyl Ligands, and Ytterbium(II) Complexes with Bridged Indenyl Ligands
[eta(5):eta(5)-(CH2)(2)(C9H5SiMe3)(2)]Yb center dot dme (5) or [eta(5):eta(5)-(CH3)(2)Si(C9H6)(2)]Yb center dot tmeda (6), respectively. Interaction of the ytterbium(III) amide [eta(5):eta(5)-(CH2)(2)(C9H6)(2)]YbN(SiMe3)(2) with excess tmeda afforded the ytterbium(II) complex [eta(5):eta(5)-(CH2)(2)(C9H6)(2)]Yb center dot tmeda (7). All the compounds were fully characterized by spectroscopic methods and elemental
