Abstract
Cyclic voltammetry has been used to characterise the electrochemical reductions of the complexes cis-[MoY2(C5H10NO)2](Y = O and/or S, C5H10NOH = 1-hydroxypiperidine) in dimethylformamide. The complexes reduce at –2.50 (dioxo), –1.94 (oxothio), and –1.59 V (dithio), referenced to the ferrocenium–ferrocene couple. For the first time, electrochemical comparisons have been made within an homologous series of molybdenum(VI) complexes.The results are especially relevant to the chemical differences between the molybdenum centres of intact and desulpho xanthine oxidase and xanthine dehydrogenase.Keywords
