摘要： A class of metallocene compounds is disclosed having general formula (I) or (Ib): wherein R1 are hydrocarbon groups; R2 are hydrogen or hydrocarbon groups, M is a transition metal of group 3, 4, 5, 6 or to the lanthanide or actinide groups in the Periodic Table of the Elements (new IUPAC version), M' is transition metal selected from those belonging to group 3 or to the lanthanide or actinide groups in the Periodic Table of the Elements (new IUPAC version), X is a monoanionic ligand, p is an integer of from 0 to 3, being equal to the oxidation state of the metal M minus two, q is an integer from 3 to 5, and n is an integer from 1 to 4, when the six-membered rings of the compound of formula (Ia) are not perhydrated, and is an integer for from 0 to 4, when the six-membered rings of the compound of formula (Ia) are perhydrated as well as in the compound of formula (Ib). These metallocenes are useful as catalyst components for the polymerisation of olefins.
