represented by the formula:
wherein each R1, R2, R3, and R4 is, independently, hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group, aryl group, substituted aryl group, or a heteroatom-containing group, provided that any of adjacent R1, R2, R3, and R4 groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated; M is a Group 4 transition metal; z is 0, 1, 2, 3, 4, 5, 6, 7, or 8 indicating the number of R' groups bound to the bridging group T, p is 1, 2 or 3 indicating the number of L groups bound to the bridging group T; each X is, independently, selected from the group consisting of hydrocarbyl radicals having from 1 to 20 carbon atoms, hydrides, amides, alkoxides, sulfides, phosphides, halides, dienes, amines, phosphines, ethers, and combinations thereof, provided that two X's may form a part of a fused ring or a ring system; T is a bridging group; each R' is, independently, hydrogen, a C1 to C10 alkyl group, a C6 to C24 aryl group, or a C7 to C40 alkylaryl group; each L is selected from the L-list, and JS'z*-1-y is a heteroatom ligand in which J is an element from Group 15 with a coordination number of 3 or an element from Group 16 with a coordination number of 2; S' is a radical group which is a hydrocarbyl, substituted hydrocarbyl, or heteroatom; and z* is the coordination number of the element J, and y is 0 or 1, are provided.
