Zusammenfassung:<正> In two previous papers, we reported the syntheses of cyclopentadienyl dichlorides of lower lanthanides and their catalytic activities of polymerization for dienes. A new series of organolanthanides containing the indenyl group and having the formulae C9H7LnCl2·（C4H8O）x（Ln=Nd,Pr,Gd, and Sm; C9H7=indenyl; C4H8O=tetrahydrofuran; x=0,1,2,3） and C9H7LnCl2·HCl·（C4H8O）x （Ln=Nd, Pr, and Sm;x=0,1,2） have also been synthesized.
