摘要

The solvated ytterbium alkyl Yb(CH(2)tBu)(3)(thf)(2) (1) was obtained in moderate yield from the reaction of ytterbium metal with neopentyl iodide. Ruby-red air-sensitive crystals of 1 were characterized by melting point, elemental analysis, IR, NMR, and UV/Vis spectroscopy and by X-ray crystallography. In the solid state the ytterbium atom shows a trigonal bipyramidal coordination with the neopentyl groups and the THF ligands occupying equatorial and axial positions, respectively. [References: 28]
