| Fig. 10. (a-c) Molecular structures of complex 8a, the nitride complex 8b, and [HIPTN3N]Mo(N2) (9a). (d) Cyclic voltammograms of 0.5 mmol·L-1 8a (red trace), 50 mmol·L-1 [ColH][OTf] (blue trace), and 0.5 mmol·L-1 8a with 50 mmol·L-1 [ColH][OTf] (purple trace) were recorded in THF containing 100 mmol·L-1 [Li][NTf2]. The MoIII/II couple around −1.80 V (red) is enhanced upon adding [ColH][OTf], giving a catalytic current consistent with N2R at potentials anodic to the background HER (blue). (e) Cyclic voltammograms of 8b recorded with and without [ColH][OTf] show a MoV/IV couple (−1.2 V vs. Fc+/0) and a cathodic MoIV/III reduction (−2.5 V vs. Fc+/0); addition of [ColH][OTf] generates an enhanced wave near −1.8 V vs. Fc+/0.
