本文报道了四种新型桨轮化合物[MnO_2(SnO_5)_4CL](n_−~(1))+(Mn~+=Na~+，Ca~(2+)，Sr~(2+)，Y~(3+)；HSNO_5~+=一硫代丁二酰亚胺)的合成、结构表征和电化学性质。通过改变Mn+阳离子的电荷和大小，我们证明了一种容易地调节Mo6点四键、Mo四键和[Mo2]4+/5+氧化还原电势的Lewis酸度的方法。随着Mn+阳离子电荷的增加，远端的Mo原子变得更加酸性，导致Mo2-Cl键的距离变短，[Mo2]4+/5+氧化还原对变得更难进入。随着Mn+⋯Mo2距离的增加，远端的Mo原子变得不那么酸性，导致Mo2-Cl键距离变长。
The syntheses, X-ray structural characterizations, and electrochemical properties of four new paddlewheel [MMo2(SNO5)4Cl](n−1)+(Mn+= Na+, Ca2+, Sr2+, Y3+; HSNO5 = monothiosuccinimide) compounds are described here. By changing the Mn+cation charge and size, we demonstrate a method for easily tuning the Lewis acidity of the Mosix-point quadruple bondMo quadruple bond and the [Mo2]4+/5+redox potential. As the charge of the Mn+cation is increased, the distal Mo atom becomes more Lewis acidic, leading to a shorter Mo2–Cl bond distance, and the [Mo2]4+/5+redox couple becomes less accessible. As the Mn+⋯Mo2distance is increased, the distal Mo atom becomes less Lewis acidic, leading to a longer Mo2–Cl bond distance.
