An oxygen-bridged bimetallic complex of the general formula (I)
Cp2R1M1-O-M2R22Cp (I),
wherein
Cp
is independently a cyclopentadienyl, indenyl or fluorenyl
ligand which can be substituted, or a ligand isolobal to
cyclopentadienyl,
R1, R2
independently are halide, linear or branched or cyclic
alkyl, aryl, amido, phosphido, alkoxy or aryloxy groups,
which can be substituted,
M1
is Zr, Ti or Hf, and
M2
is Ti, Zn, Zr or a rare earth metal.
The complex can be useful as a polymerization catalyst.
