摘要：
Bis(2-methoxyethylcyclopentadienyl) divalent solvent-free organolanthanide complexes (MeOCH2CH2C5H4)2Sm (1) and (MeOCH2CH2C5H4)2Yb (2) have been synthesized by the interaction of (MeOCH2CH2C5H4)K with LnI2(Ln=Sm, Yb). Recrystallization of 2 from THF produced the solvated single crystal (MeOCH2CH2C5H4)2Yb.OC4H8 (3) which has the coordination number of nine, the highest yet reported for this class of compound. The two ring centroids of the 2-methoxyethylcyclopentadienyl rings, the two oxygen atoms of ether-substituted groups on the rings and the oxygen atom of the THF form a distorted trigonal bipyramid around the central ion of ytterbium.
