Di- and tri-valent complexes of ytterbium via novel metal oxidation
Abstract
Oxidation of Yb metal by iodopentamethylcyclopentadiene (IC5Me5) afforded Li[Yb(C5Me5)I3] and Li[Yb(C5Me5)2I2] sequentially in the presence of LiI; analogous anionic chloride complexes, the new divalent complex Yb(C5Me5)2, and methyl derivatives of both di- and tri-valent systems were obtained via metathetical reactions.
