Abstract of the Disclosure: An organometal complex is provided which is represented by the general formula (1) below: Image (1) wherein Cp1 and Cp2 are respectively a substituted or unsubstituted cyclopentadienyl group; R1 is a group selected from alkylene groups or arylalkylene groups having 1 to 20 carbons, dialkylsilylene groups, dialkylgermanylene groups, alkylphosphinediyl groups, or alkylimino groups, and R1 crosslinking Cp1 and Cp2 together m is 0 or 1; M is selected from titanium, zirconium, and hafnium; R2, R3, and R4 are independently hydrogen, a hydrocarbon group of 1 to 12 carbons, an alkoxyl group, or an aryloxy group; and MAO is a methylalumoxane group. This organometal complex is capable of producing selectively an olefin polymer without use of any other additional catalyst component.
