There is no measurable difference in the primary oxidation potentials of the CI.T and/rons isomers of the Mo or of W dinitrogen complexes. Moreover, the primaiy redox potentials of the complexes of these two different metals are also remaikably similar, as is generally observed for their 17-electron/ 18-electron couples [12-14]. 

Structure, spectroscopic properties, reactivity and redox potentials have been correlated for octahedral dinitrogen complexes of Mo, W and Re bearing a wide range of ligands trans or cis to dinitrogen [11,12,15-17]. This work and earlier ideas [18] led to the suggestion...

The complicated redox chemistry of NO c species is both a blessing and a curse in this endeavor, as is illustrated in Figure 4. i. Unlike SO c chemistry, many NO c species are stable and may be used directly as substrates or analyzed for as products these include nitrate, nitrite, hydroxylamine, and ammonia and the gases nitric oxide, nitrous oxide, and dinitrogen. Still, there remains much confusion about NO c chemistry, for example the potential of the simple one-electron reduction of nitric oxide (NO) to the nitroxyl (NO ) state has been widely misrepresented, a recent re-evaluation has set it at ca. -800 mVNHE, a revision of more than one volt from previously cited values. Likewise, the pA"a of the...
