Abstract

The present invention relates to a metallocene compound of the formula I EQU R.sup.5.sub.n Cp.sup.1 Cp.sup.2 M.sup.1 R.sup.1 R.sup.2 (I) where Cp.sup.1 and Cp.sup.2 are, independently of one another, identical or different and are each an unsubstituted or substituted cyclopentadienyl group, n=zero or 1, R.sup.5 is a bridge, M.sup.1 is a metal of group IVb, Vb or VIb of the Periodic Table of the Elements, R.sup.1 and R.sup.2 are identical or different and are each a hydrogen atom or a C.sub.1 -C.sub.40 -group, wherein at least one of the two groups Cp.sup.1 and Cp.sup.2 is a substituted cyclopentadienyl group which bears at least one cyclic C.sub.3 -C.sub.30 -group containing at least one heteroatom in the ring, or which bears a fused-on C.sub.2 -C.sub.30 ring system containing at least one heteroatom in the ring. The metallocene compound can be used as a catalyst component for olefin polymerization.
