Heptamethylindenyl complexes of lanthanum, neodymium and erbium were synthesized by the reaction of the appropriate rare earth trichloride with potassium heptamethylindenide in tetrahydrofuran by Tsutsui et al. in 1982. Corresponding to the ratio of the starting materials, the tris(heptamethylindenyl) derivatives of...
