摘　　要：Some novel manganese and nickel complexes were synthesized by reacting manganese(II)dichloride and nickel(II)dichloride with pyridyl-imine ligands differing in the nature of the substituents at the imino nitrogen atom.All the complexes were characterized by analytical and infrared data:for some of them single crystals were obtained,and their molecular structure was determined by X-ray diffraction.The complexes were used in association with methylaluminoxane(MAO)for the polymerization of 1,3-butadiene obtaining active and selective catalysts giving predominantly 1,2 polybutadiene in case of manganese catalysts and exclusively cis-1,4 polybutadiene in case of nickel catalysts.
