A butadienyl bridge between two nickel atoms , which, in addition, carries N ligands of the diazadiene type, is formed on reaction of mononuclear diazadienenickel complexes with disubstituted acetylenes. The pattern of substitution of the C 4 ‐bridge is the same as that of the octatetraene formed from the same educts. These findings are a further indication of binuclear catalysts in the formation of COT from alkynes.
