It has often been claimed that the syntheses of bis(cyclopentadienyl) chloride complexes of the larger lanthanides fail for steric reasons, and that the use of bulky substituted cyclopentadienyl ligand such as C/sub 5/(CH/sub 3/)/sub 5/ should allow the isolation of these important compounds which then could be used in organolanthanide synthesis. By following this idea, crystalline bis(pentamethylcyclopentadienyl) complex of neodymium was successfully isolated and characterized. The reaction of NdCl/sub 3/ with 2 equiv of LiC/sub 5/Me/sub 5/ forms a crystalline product which was formulated as ((C/sub 5/Me/sub 5/)/sub 2/NdCl/sub 2/)(Li(C/sub 4/H/sub 8/O)/sub 2/) based on complete elemental analysis and spectral data.
