The planar‐tetracoordinate carbon compound 4 exchanges the bridging μ‐(η 1 ‐ C :η 2 ‐ C,C )‐2‐butyne ligand for p ‐tolunitrile in dichloromethane at 90°C to yield the [μ‐(η 1 ‐ N :η 2 ‐ C,N )‐aryl cyanide]dizirconium cation complex 2a. X‐ray diffraction revealed an aza‐allenyl‐type character of the RCNZr moiety in this thermodynamically favored (μ‐nitrile)zirconium cation complex.
