Abstract: The invention relates to transition metal complexes of general formulas (Ia) or (Ib) in which the substituents and indices have the following meanings: M represents titanium, zirconium, hafnium, vanadium, niobium or tantalum or an element of the third subgroup of the periodic table or of the lanthanides; X represents fluorine, chlorine, bromine, iodine, hydrogen, C1-C10-alkyl, C6-C15-alkyl aryl having 1 to 10 C-atoms in the alkyl residue and 6 to 20 C-atoms in the aryl residue, -OR or -NR R ; n represents 1, 2, or 3, whereby n corresponds to the valence of M minus the number 2; Y represents (a), (b), (c) or (d); Z represents a triple-linking binding group and; A and A represent double-linking binding links. The invention also relates to a method for producing the transition metal complexes, to their production as compounds used as intermediate products, and to the use of transition metal complexes for the polymerization of olefins. Further, the invention relates to a method for the polymerization of olefins, homopolymerizates or copolymerizates of ethylene or of propylene having other C2-C12-alk-1-enes, to their use for producing films, fibers or shaped bodies, and to the films, fibers and shaped bodies made of these polymerizates.
