摘要 |
Metallocene compounds having the general formula (I):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;M' is a transition metal selected from those belonging to group 3 or to the lanthanide or actinide groups in the Periodic Table;X is a monoanionic ligand;p is an integer of from 0 to 3, being equal to the oxidation state of M minus two;q is an integer from 3 to 5; andn is an integer from 1 to 4, when the six-membered rings of formula (Ia) are not perhydrated, and is an integer of from 0 to 4, when the six-membered rings of formula (Ia) are perhydrated as well as in the compound of formula (Ib). |
