The present invention relates to a metallocene compound of the formula I R5nCp1Cp2M1R1R2 (I) where Cp1 and Cp2 are, independently of one another, identical or different and are each an unsubstituted or substituted cyclopentadienyl group, n = zero or 1, R5 is a bridge, M1 is a metal of group IVb, Vb or VIb of the Periodic Table of the Elements, R1 and R2 are identical or different and are each a hydrogen atom or a C1-C40-group, wherein at least one of the two groups Cp1 and Cp2 is a substituted cyclopentadienyl group which bears at least one cyclic C1-C30-group containing at least one heteroatom in the ring, or which bears a fused-on C2-C30 ring system containing at least one heteroatom in the ring. The metallocene compound can be used as a catalyst component for olefin polymerization.
