An oxygen-bridged bimetallic complex of the general formula (I)n nCp 2 R 1 M 1 -O-M 2 R 2 2 Cp (I),n nwhereinn Cp is independently a cyclopentadienyl, indenyl or fluorenyl ligand which can be substituted, or a ligand isolobal to cyclopentadienyl, R 1 , R 2 independently are halide, linear or branched or cyclic alkyl, aryl, amido, phosphido, alkoxy or aryloxy groups, which can be substituted, M 1 is Zr, Ti or Hf, and M 2 is Ti, Zn, Zr or a rare earth metal. nn The complex can be useful as a polymerization catalyst. |
