    摘要： The invention relates to metallocene compounds having the formula (I): (CpYq)mMRnBo  (I) wherein: Cp or each same or different Cp is a non-substituted or substituted, fused or non-fused, homo(iso)cyclic or heterocyclic cyclopentadienyl ligand, indenyl ligand, tetrahydroindenyl ligand, fluorenyl ligand or octahydrofluorenyl ligand, Y or each same or different Y is a substituent at the cyclopentadienyl ring of said ligand Cp having the following structure (II): wherein: D is an element of Group 14 of the Periodic Table (IUPAC), R1, R2 and R3 are the same or different and are each one of a hydrogen, a halogen, a substituted or unsubstituted C1-C10 hydrocarbyl group, a substituted or unsubstituted C1-C10 hydrocarbyloxy group, a C1-C12 organosilicon group, or at least two of R1, R2 and R3 form together with D a C4-C20 ring structure; M is a transition metal of Group 4 of the Periodic Table (IUPAC) and is bound to the ligand Cp or ligands Cp in an &eegr;5 bonding mode; R or each same or different R is bound to M and is one of a hydrogen, a halogen, a substituted or unsubstituted C1-C10 hydrocarbyl group, a substituted or unsubstituted C1-C10 hydrocarbyloxy group, a C1-C12 organosilicon group, or two R form together with M a C4-C20 metallocyclic ring structure; B is a bridge atom or group between two Cp ligands or between one Cp ligand and M; q is, when Cp is non-bridged, 0-5 for the cyclopentadienyl ligand, 0-3 for the indenyl or tetrahydroindenyl ligand and 0-1 for the fluorenyl or octahydrofluorenyl ligand, q is, when Cp is bridged, 0-4 for the cyclopentadienyl ligand, 0-2 for the indenyl or tetrahydroindenyl ligand and 0 for the fluorenyl or octahydrofluorenyl ligand; m is 1 or 2; m·q≧1; o is 0 or 1; and n is 4-m-o, except when there is one bridge B between two Cp ligands, in which case n is 4-m, their intermediates, preparation and use.
