An asymmetrically bridging aryldiamine ligand is the salient structural feature of the binuclear complex 1 , formed from the corresponding alkylidenetantalum complex and neopentylzinc chloride with elimination of neopentane. The structural data indicate that the TaCZn bridge lies midway in character between a three‐center two‐electron bond and a combination of a TaC σ bond and a coordinative C→Zn bond.
