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, which they are attached to, 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 heteroaryl group, C7-13arylalkyl group or C7-12 alkylaryl group; and, R6 is hydrogen, C6-12 aryl group or C7-12 alkylaryl group.
