An organometallic compound of the formula I where M1 is selected from among Fe, Ru and Os and M2 is selected from among the transition metals of groups IV to VI of the Periodic Table, which can be prepared by reacting an organometallic compound of the formula II with a transition metal compound of the formula III, <paragraph lvl="0"><in-line-formula>M2L1L2(L3)x+1 III</in-line-formula>where the variables are as defined above and the organometallic compound of the formula II can, if desired, be doubly deproteinated beforehand, can be used as part of a catalyst system for the polymerization or copolymerization of olefins. This catalyst system comprises one or more organometallic compounds of the formula I and at least one activator. The compound of the formula I can also be used to produce a solid catalyst comprising at least one organometallic compound of the formula I, at least one activator and a solid support by impregnating a support material with one or more organometallic compounds of the formula I and at least one activator. This solid catalyst can be used in a process for the polymerization or copolymerization of olefins in bulk, in suspension or in the gas phase.
