A tin-supported iron catalyst produces 5.9 turnovers of NH3 from N2, using [Ph2NH2]OTf as the acid and CoCp2* as the reductant. Two redox states of the Fe(N2) adduct and an Fe silyldiazenido complex were characterized using X-ray crystallography along with NMR and Mössbauer spectroscopies. Density functional theory calculations reveal that the charge on the Sn center correlates strongly with both the polarization of the N2 moiety and the charge on the distal N atom.
