    Abstract: The invention relates to a metallocene complex according to formula 1 wherein M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements, Q is an anionic ligand to M, X is a cyclic bridging group that is bonded to a carbon atom of the cyclopentadienyl ligand and to nitrogen, Z 1 , Z 2 , Z 3 and Z 4 are identical or different and can be chosen from hydrogen or a hydrocarbon radicals; adjacent substituents Z can form a ring, R is chosen from hydrogen or a hydrocarbon radical with 1-20 carbon atoms. Also claimed are compositions comprising the metallocene complex, a process for the preparation of said complex and a process for the polymerization of olefin polymers in the presence of the metallocene complex. A particular embodiment is the following complex: formula 5
