Abstract
The metallocene complexes according to the present invention are prepared by reacting a transition metal complex of Group III-X of the Periodic Table, having at least one cycloalkanedienyl group, with a compound having at least two functional groups. The transition metal complex has a main ligand such as a cycloalkanedienyl group and at least one ancillary ligand which coordinated to a transition metal of Group III-X. The functional groups in the compound having at least two functional group are selected from the group consisting of a hydroxyl group (--OH), a thiol group (--SH), a primary amine group (--NH.sub.2), a secondary amine group (RNH--), a tertiary amine group (RR'N) a primary phosphorous group (--PH.sub.2), a secondary phosphorous group (RPH--), a tertiary phosphorous group (RR'P), a thiirane group ##STR1## etc.
