Fig. 1. Physicochemical origins of N2 inertness and the orbital basis of transition-metal activation. (a) Representative molecular properties of N2, which highlight its strong N≡N bond, stable electronic structure, and high molecular symmetry. (b) Simplified molecular orbital diagram of N2. (c) Synergic σ-donation/π-back-donation for end-on M−N≡N binding.
