Beschreibung
Zusammenfassung:	There is provided an organometallic compound comprising a metal M of Group 3 to 6 of the Periodic Table or the Lanthanide series and at least one (hetero)cyclohexadienyl ligand of the general formula (I)C5ARnwherein A is an element chosen from Group 13 to 16 of the Periodic Table, R which can be connected to C or to A and which may form a bridge is independently hydrogen or an organic substituent which may contain one or more hetero-atoms and n is 3 plus the number of valencies of A. There is further provided the use of this compound as a catalyst, with a co-catalyst, in a process for the (co)oligomerisation or (co)polymerisation of olefinically unsaturated hydrocarbons.
