A series of homoleptic complexes with non-innocent ligands derived from N,N′-bis(pentafluorophenyl)-o-phenylenediamine (H2 Fpda) are reported. [NiII(Fsbqdi)2] (1), [PdII(Fsbqdi)2] (2), [Co II(Fsbqdi)2] (3), and [CuII( Fsbqdi)2] (4) were synthesized, where ( Fsbqdi)1- represents a radical anion formed by one-electron oxidation of the doubly deprotonated H2Fpda. The oxidation states of ligands and metals in complexes 1-4 were assigned by single crystal X-ray crystallography performed at low temperatures. Complex 4 is the first CuII complex where both o-phenylenediamine derived ligands are monoanionic radicals. The bulky N-C6F5 substituents force the complexes 1, 3, and 4 to adopt a twisted geometry (intermediate between square-planar and tetrahedral). The electronic structures of the neutral compounds 1-4 and of some of their cationic and/or anionic neighboring redox states were probed using EPR and UV-VIS-NIR spectroelectrochemistry. The twisted geometry of the complexes results in considerable changes in their electronic structures compared to the well known square-planar complexes while the strongly electron withdrawing N-C6F5 groups have a great influence on redox properties.

The present invention describes methods of making a series of amine-containing organic compounds which are used as ligands for group 3-10 and lanthanide metal compounds. The ligands have electron-withdrawing groups bonded to them. The metal compounds, when combined with a cocatalyst, are catalysts for the polymerization of olefins.
