<P>PROBLEM TO BE SOLVED: To provide a heterobimetallic transition metal complex utilizable as a homogeneous catalyst, etc. <P>SOLUTION: The metal complex represented by formula (1) (wherein, M<SB>1</SB>denotes a tri-, a tetra- or a pentavalent transition metal; M<SB>2</SB>denotes a transition metal; X denotes a hydrogen atom, a halogen atom, a 1-20C hydrocarbon group or an alkoxy group or an amino group: n is an integer of 1-3; R<SP>1</SP>denotes a 1-20C hydrocarbon group or a hydrocarbon group having a silicon atom; R<SP>2</SP>denotes a 1-20C hydrocarbon group; a hydrocarbon group having a silicon atom or an alkoxy group or an amino group; Z denotes an oxygen atom, a sulfur atom or an NR (wherein, R denotes an alkyl group) when Z is present; L denotes a halogen atom, a 1-20C hydrocarbon group or an akoxy group, a carbonyl group, phosphines, isonitriles, ethers or sulfides; and m denotes an integer of 2-4) or a dimer thereof is obtained. The metal complex is used as a catalyst for polymerizing olefins. <P>COPYRIGHT: (C)2004,JPO |
