Abstract: The present invention relates to a metallocene complex with a heteroatom-containing π-ligand, having a chemical structure represented by formula (I) as below: wherein M is a transition metal element from Group 3, Group 4, Group 5 and Group 6 in the periodic table, including lanthanides and actinides; X, being the same as or different from each other, is selected from hydrogen, halogen, an alkyl group R, an alkoxyl group OR, a mercapto group SR, a carboxyl group OCOR, an amino group NR2, a phosphino group PR2, —OR∘O— and OSO2CF3; n is an integer from 1 to 4 and is not zero; the charge number resulted from multiplying n by the charge number of X equals to the charge number of the central metal atom M minus 2; Q is a divalent radical; A is a π-ligand; and Z is a π-ligand; the process for producing the same; a catalyst system of the same; and use of the catalyst system.
