Abstract: An organometallic complex, a catalyst composition employing the same, and a method for preparing polyolefin are provided. The organometallic compound has a structure represented by Formula (I)





, wherein M is Ti, Zr, or Hf; X is —O—, or —NR6—; R1 and R2 are independently hydrogen, C1-6 alkyl group, C6-12 aryl group, or R1 and R2 are combined with the carbon atoms, to which they are attached, to form an C6-12 aryl moiety; R3, R4 and R5 are independently fluoride, chloride, bromide, C1-6 alkyl group, C6-12 aryl group, C3-6 hetero aryl group, C7-13 aryl alkyl group or C7-12 alkyl aryl group; and R6 is hydrogen, C6-12 aryl group or C7-12 alkyl aryl group.
