Coordination compounds of iron(II)chloride with bis(imino)pyridine ligands bearing -alkenyl substituents were synthesized and characterized. They can be activated with methylalumoxane (MAO) and then be used as self-immobilizing catalysts for the polymerization of ethylene. The produced polyethylene
