Abstract

The novel binuclear neutral nickel(II) complex [((2,6-iPr₂C ₆H₃)NCH)C₆H₃ONi(PPh ₃)Ph]₂ (5), based on the 3,3′-bisalicylaldimine ligand, has been synthesized in high yield, and its structure has been confirmed by X-ray crystallography, elemental analysis, and ¹H NMR and ¹³C NMR spectra. Used in the polymerization of ethylene as an active single-component catalyst, the complex exhibited a high catalytic activity of up to 4.55 × 10⁵ g of PE/((mol of Ni) h), and polyethylenes with a weight-average molecular weight (M̄_w) of up to 487.7 kg/ mol and relatively broad molecular weight distribution (M̄_w/ M̄_n = 2.8-3.8) were produced.
