摘要
Reaction of anhydrous ytterbium trichlorides with 2 equiv. of cyclopentylindenyl lithium in THF solution, followed by removal of the solvent and crystallization of the product from diethyl ether, affords a crystal complex of the composition (C 5H 9C 9H 6) 2Yb( μ Cl) 2Li(Et 2O) 2. Crystallographic analysis shows that the ytterbium coordinated by two cyclopentylindenyl rings and lithium surrounded by two ether molecules are bridged by the two chlorine atoms and Yb, Li and two chlorine atoms form a plane.
