The invention relates to a metallocene complex according to formula (I), (I) wherein R1 and R2 are independently selected from H, an alkyl or an aryl group, wherein R3 is a C1 -C10 alkyl group, wherein R' is selected from H, an alkyl group, an aryl group and wherein different R' substituents can be connected to form a ring structure and wherein B is a 1,2 phenylene bridging moiety, which can be optionally substituted, wherein Mt is selected from Ti, Zr and Hf, X is an anionic ligand, z is the number of X groups and equals the valence of Mt minus 2. The invention also relates to a catalyst comprising the reaction product of the metallocene complex and a cocatalyst. Further the invention relates to a (co)polymerisation process of olefinic monomers.
