In this contribution the synthesis and characterization of two distinct, yet similar, zirconium complexes, [(?-P-nacnac-CN)Cp] and [(?-nacnac-CN)Cp] zirconium dichloride were discussed. In addition to the complexes, Lewis acid adducts [B(C 6F 5) 3] of the complexes were isolated and characterized as well. It was found that while structurally similar, the complexes behave distinctly upon adduct formation and in their ethylene polymerizations. © 2012 The Royal Society of Chemistry.
