New organolanthanide complexes [Li(THF)2]2(m-Cl)4(h5-C5H5)Ln譚HF (Ln = La, Nd) were prepared in good yield by treating LnCl3-LiCl with equimol. amount of C5H5Na in THF. The products were easy to recrystallize and can be used for preparation of cyclopentadienyl rare earth derivatives The complexes were characterized by elemental anal., IR, and x-ray diffraction.
