Abstract
A tetrahedrally coordinated L_3Fe−N_x platform that accommodates both terminal nitride (L^3Fe^(IV)_≡N) and dinitrogen (L_3Fe^I−N_2−Fe^IL_3) functionalities is described. The diamagnetic L_3Fe^(IV)_≡N species featured has been characterized in solution under ambient conditions by multinuclear NMR (^1H, ^(31)P, and ^(15)N) and infrared spectroscopy. The electronic structure of the title complex has also been explored using DFT. The terminal nitride complex oxidatively couples to generate the previously reported L_3Fe^I−N_2−Fe^IL_3 species. This reaction constitutes a six-electron transformation mediated by two iron centers. Reductive protonation of the nitride complex releases NH_3 as a significant reaction product.
