The article conveys some information:<\/p>\n<p>New chromium(III) [Cr(III)] catalysts based on 2,6-bis(1-pyrazolylmethyl)pyridine derivatives have been synthesized, characterized, and evaluated for ethylene polymerization All ligands with substituents on the pyrazole rings were analyzed by single-crystal X-ray diffraction to clearly identify isomer structures. Addnl., X-ray analyses of a new Cr(III) complex bearing 2,6-bis[(4,5-dimethyl-1H-pyrazol-1-yl)methyl]pyridine showed tridentate coordination on the mer-octahedral chromium sphere. Upon activation with dry Me aluminoxane, the precatalysts produce polyethylene (PE) as a major product, and their catalytic performances were affected by the substituents on the pyrazole units; the introduction of functional groups on the pyrazole compositions and the mol. weight of the PE.
