A new, extensive series of mono-dinitrogen complexes was reported. These were the first reported mono-N2 complexes to afford, upon treatment with excess acid in solution, more than a trace of ammonia and/or hydrazine. The sodium amalgam reduction of MoCl3(Triphos}, where Triphos = PhP(CH2CH2PPh2)2, in tetrahydrofuran solution in the presence of 2L or L2 [where L = PMe2Ph, lA; Me2PCH2PMe2, 2B; 1,2-(Me2As)2CSH4, 4C; Ph2PCH2PPh2, SD; Ph2PCH2CH2PPh2, 6E; and 1,1'-(Ph2PC5H4)2Fe), 7F] with a stoichiometric amount of dinitrogen led to the formation of Mo(N2)(Triphos)(L2) in high yields.
