Abstract

The present invention relates to a metallocene compound of the formula I, ##STR1## where Cp is an unsubstituted or substituted cyclopentadienyl group, Ind is unsubstituted or substituted indenyl, M is a tetravalent metal, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are, independently of one another, identical or different and are each a hydrogen atom or a C.sub.1 -C.sub.20 -hydrocarbon radical, R.sup.5 and R.sup.6 are, independently of one another, identical or different and are each a hydrogen atom or a C.sub.1 -C.sub.20 -hydrocarbon radical, m is 1 or 2 and k and l are 1 when m is 1 when m is 1 and k and l are zero when m is 2. The metallocene compound is suitable as a catalyst component for olefin polymerization.
