  This invention provides a metallocene complex and the preparation method thereof and a catalyst composition. This catalyst composition comprises a metallocene complex represented by formula (I) and an organic boron salt. Compared to the prior art, the catalyst used in this invention, which is the metallocene complex represented by formula (I), does not contain any side chain, and the coordination space of the central metal has a large opening degree. Therefore, the catalytic activity for more sterically hindered monomers is higher, and the comonomer incorporation is also higher. Furthermore, the metallocene complex represented by formula (I) used in this invention is a heterocyclic ring fused cyclopentadienyl ligand. Heterocyclic rings have relatively strong electron-donating capacity. By fusing a cyclopentadienyl group using heterocyclic rings, it is possible to change the electronic effect of the metal center and in turn increase the activity of catalyst. Therefore, by using the metallocene complex represented by formula (I), it is possible to prepare copolymers of ethylene with other olefins at high activity and high comonomer incorporation, and it is also possible to catalyze the polymerization of styrene and substituted styrene at high syndiotacticity and high activity.
