title = "Exploring the role of pendant amines in transition metal complexes for the reduction of N2 to hydrazine and ammonia",
abstract = "This review examines the synthesis, properties, and acid reactivity of transition metal dinitrogen complexes bearing phosphine ligands containing pendant amine groups in the second coordination sphere. We have synthesized non-precious metal dinitrogen complexes containing bidentate, tridentate, and tetradentate phosphine ligands, some of which generate N2 derived ammonia and/or hydrazine in the presence of excess acid. The metal identity, metal oxidation state, ligand denticity, and functional groups on phosphorus/nitrogen all play a role in controlling the site of protonation (at the metal, pendant amine, or coordinated dinitrogen) with the addition of exogenous acid.",
