N2 - Zirconium complexes of two dianionic amine bis(phenolate) ligands have been synthesized, their X-ray structures solved, and their activity as hex-1- ene polymerization catalysts studied; upon treatment with B(C6F5)3, as octahedral [ONNO]Zr[CH2Ph]2 complex, having an extra N-donor group on a side arm, shows exceptionally high polymerization activity and yields a high molecular weight poly(hex-1-ene) whereas a related pentacoordinate[ONO]Zr[CH2]Ph)2 complex, having on extra donor group, shows only poor activity as a polymerization catalyst.
