Patent ID: 7786232

Claim:
A tridentate catalyst component of formula IV wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are each independently selected from hydrogen or unsubstituted or substituted hydrocarbyl and two or more groups can be linked together to form further ring or rings, with the restriction that R 1 and R 3 , R 2 and R 4 , and R 9 and R 10 , cannot be simultaneously oxazoline, and wherein Z is selected from groups 15 or 16 of the Periodic Table and m is the valence of Z minus one, wherein M is Ti, Zr, Hf, V, Cr, Mn, Fe, Co, Ni, or Pd, wherein X′ are the same or different and are halogen or substituted or unsubstituted hydrocarbyl; and wherein n is the valence of M and characterised in that the complex folds around the carbon atom preceding Z to allow joining Z to metal M in order to form a 3 dimensional scorpion like structure.
