✦ Synopsis

Five new hetero-bimetallic metallocene complexes were synthesized by the reaction of RCpTiCl 3 and a Si-bridged zirconocene complex in refluxing toluene. They were all well characterized. These complexes activated with methylaluminoxane (MAO) are highly active catalysts for the polymerization of ethylene. The molecular weight (M w = 28,957-124,089) and the molecular weight distribution (MWD = 2.04-3.01) of the polymer generated from the bimetallic catalytic system were higher than that obtained by Cp 2 ZrCl 2 .

Three new lanthanide (Ln)-alkylaluminium (Al) bimetallic complexes with the formula [(p-CF,CO,),Ln(p-CF,CHO2)AlR2 2THF], (Ln = Nd, Y, R = i-C4H, (i-Bu); Ln = Eu, R = C2H5(Et); THF = tetrahydrofuran) were synthesized by the reaction of Ln(CF,CO,), (Ln=Nd, Y) with HA1 (i-Bu), and of Eu(CF,CO,), with A
