The invention is directed to a metallocene complex selected from the group consisting of 2-indenyl complexes I, II, III and IV, wherein Y is a C1-C20 linear, branched or cyclic hydrocarbyl group, or a C6-C30 aryl or substituted aryl group; L is an electron-donating ligand; A is an element selected from Group 15 or 16 of the Periodic System of the Elements; R is a C1-C30 alkyl, aryl, or substituted aryl group; n is the number of R groups and is an integer from 1 to 3; m is the number of carbon atoms in the hydrocarbyl group between A and B and is an integer from 1 to 4; B is a boron atom; M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements; X is an anionic ligand to M and z is the number of X groups and equals the valence of M minus 2. The invention is also directed to a catalyst comprising a 2-indenyl metallocene complex, a ligand precursor, a process for the preparation of a ligand precursor, a process for the preparation of olefin polymers in the presence of 2-indenyl metallocene complexes, the use of the olefin polymers for making articles and articles comprising an olefin polymer.
