The invention relates to a novel group bridged metallocene transition metal complexes, wherein the complex includes at least one indenyl ligand substituted at the 4- position with a phenyl group, the 4-phenyl group being preferably substituted at the 3 ', 4', and 5' positions with particular combinations of substituents, particularly wherein the 4'- substituent is a group of the formula (XR'n)-, wherein X is a Group 14-17 heteroatom having an atomic weight of 13 to 79 and R' is one of a hydrogen atom, halogen atom, a C1-C10 alkyl group, or a C6-C10 aryl group and n is 0, 1, 2, or 3. Catalyst systems including the transition metal complex, polymerization processes using the transition metal complex, and polymers made using the transition metal complex are also described.
