Abstract
Aryldiazenido-complexes, [Mo(N2C6H4X)(S2CNMe2)3](X = a range of ortho-, meta-, and para-substituents), undergo reversible one-electron oxidation to stable cations in non-aqueous electrolytes at platinum or vitreous carbon electrodes. E.s.r. spectra indicate that the highest occupied molecular orbital (h.o.m.o.) is essentially metal in character, and plots of E½ against Hammett constants show that the influence of X on the h.o.m.o. via the –NN– linkage is primarily through an inductive rather than a resonance mechanism.Keywords
