摘要：

Lithium and zirconium complexes [Li-2(B)(tmen)](2) 4, [Li-4(C)(2)(tmen)] 5, [Zr(B)(2)] 7 and [Zr(C)(2)] of the new ligands eta(5)-C5H4Si(Me)(2)C(H)SiMe3 (=[B](2-)) and eta(5)-C5H4Si(Me)(2){NC(Bu-t)C(H)SiMe3}(-) (=[C](2-)) are reported, as well as the X-ray structures of the centrosymmetric dimer 4 and of 5 (having each of the four Li atoms in a different environment) and the catalytic activity of 7 for alpha-alkene polymerisation.
