摘要

Making Ns meet: Triphenylphosphinazine N₂(PPh₃) ₂ is a donor-acceptor complex between nitrogen in the highly excited ¹Γ_g state and two anti-periplanar coordinated phosphine ligands (see structure). Although the dissociation into N ₂+2 PPh₃ is calculated to be exergonic by 75 kcal mol ^-1, the compound is kinetically very stable as a result of the very large Lewis acidity of N₂ in the excited ¹Γ _g state.
