This paper deals with the electrochemical studies performed in DMF on three iso-electronic compounds of general formula γ-[SiW₁₀O₃₆(M₂O₂E₂)]⁶⁻, which differ either with respect to the nature of their metallic centers (M = Mo(V) or W(V)) or the nature of the bridges between the Mo(V) atoms (E = O²⁻ or S²⁻). Interestingly, cyclic voltammetry experiments performed in dry DMF revealed electrochemical processes both in oxidation and reduction modes. The nature of these processes is studied and elucidated by various electrochemical techniques such as coulometry, rotating disk voltammetry, spectro-electrochemistry (IR and UV-Vis), and NMR and DFT calculations.

[SiW ₁₀ O ₃₆（M ₂ O ₂ E ₂）] ^6-多金属氧酸盐系列的电化学性质（M = Mo（v）或W（v）； E = S或O）†

本文涉及在DMF中对三种通式γ-[SiW ₁₀ O ₃₆（M ₂ O ₂ E ₂）] ^6−的等电子化合物进行的电化学研究，这些化合物的金属中心性质不同（M = Mo（V）或W（V））或Mo（V）原子之间的桥的性质（E = O ²⁻或S ²⁻）。有趣的是，在干DMF中进行的循环伏安法实验揭示了氧化和还原模式下的电化学过程。通过各种电化学技术（例如电量分析法，旋转盘伏安法，光谱电化学法（IR和UV-Vis）以及NMR和DFT计算）研究并阐明了这些过程的性质。
