- 3. A metallocene complex as claimed in claim 1, in which X is chlorine or bromine.
- 4. A metallocene complex as claimed in claim 1, in which Y is carbon, sulfur or silicon.
- 5. A metallocene complex as claimed in claim 1, wherein R.sup.1 and R.sup.2 are identical or different and are each methyl, ethyl, isopropyl or tert-butyl.
- 6. A metallocene complex as claimed in claim 1, in which two adjacent radicals R.sup.3 and R.sup.4 and R.sup.5 and R.sup.6 in each case together form a hydrocarbon ring system of 10 to 12 carbon atoms.
