Carbonylation of the strongly activated hafnocene dinitrogen complex, [{(η 5 ‐C 5 H 2 ‐1,2,4‐Me 3 ) 2 Hf} 2 (μ 2 ,η 2 ,η 2 ‐N 2 )], in the presence of electron‐rich 4‐substituted pyridines resulted in isolation of rare μ‐nitrido hafnocene complexes prepared from N 2 cleavage. The electronic and molecular structures as well as the intermediacy in NC bond forming reactions has been determined.
