Patent ID: 7847099

Claim:
A non-metallocene organometallic complex comprising a tridentate ligand, wherein the tridentate ligand is a dianionic or trianionic ligand having the structure of formula wherein L is an atom that when contacted with a metal can donate one or more of its electrons through a coordinate covalent bond to, or shares its electrons through a covalent bond with the metal Z is a group 14, a group 15 or group 16 anionic donor, Y is a an organic fragment selected from the group consisting of a hydrocarbylene, substituted hydrocarbylene, heteroatom-containing hydrocarbylene or substituted heteroatom-containing hydrocarbylene linker, wherein Y and L are linked together to form a cyclic group; R, R 1 R′ and R′ 1 are independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom containing hydrocarbyl, or other functional group, α and β are independently single or multiple bonds; and n is 0, 1 or 2 wherein the metal, R, R 1 , and the cyclic group are selected to provide the resulting non-metallocene organometallic complex with a Cs geometry, a C 1 geometry, a C 2 geometry or a C 2v geometry.
