AbstractDisclosed herein are compounds shown as Formula I: wherein R<1>-R<11 >are each independently selected from a group comprising hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl, and substituted heterohydrocarbyl containing 1 to 20 carbon atoms and two or more of the R<1>-R<11 >groups may be joined to form cyclic versions; R<1>-R<11 >can also be selected from hydrogen, halogen, and recognized donor and acceptor groups; E is a Group 16 element (including oxygen); M is a metal selected from the group comprising Group 3 to 10 elements (including titanium and zirconium) and the Lanthanide series elements; m is the oxidation state of the metal; X is a monovalent atom or group bonded to M; Y is a mono- or bidentate molecule datively bound to M, and n is zero or an integer up to five. These catalysts, when combined with a suitable activator, are active for the polymerization of olefins.
