The first defined complex for oligo‐ and polymerization of ethylene which requires no co‐catalyst is the crystalline nickel complex (1) . Its structure was established by X‐ray analysis. Dissolved in toluene, compound (1) reacts with ethylene (50 bar) at 50°C giving almost exclusively linear α‐olefins; linear polyethylene is formed under a different set of conditions.
