Abstract: A transition metal compound having a novel structure is disclosed herein. The transition metal compound can have improved structural stability by forming a stable coordination site of a transition metal through controlling a bond angle formed by the amido group of a phenylene bridge, a cyclopentadienyl ring, and a transition metal. The transition metal compound has excellent copolymerization properties and may produce an olefin polymer having a high molecular weight in a ultra low density region.
