The high-nuclearity polyoxothiomolybdate H(8)Mo(84)S(48)O(188)(H(2)O)(12)(CH(3)COO)(24) has been prepared and characterized by single-crystal X-ray crystallography and (1)H NMR, IR, Raman, and UV-vis spectroscopy. The solid-state structure reveals an unprecedented and intriguing arrangement consisting of a nanoscaled anionic cube. The surprisingly open structure of this {Mo(84)}-type cubic box features a large inner void that is accessible via its six open square faces with diameters of ca. 9 Å. Importantly, this molecular system appears to be highly functionalizable because of the presence of 24 exposed exchangeable acetate ligands.
高核多氧代硫钼酸盐 H(8)Mo(84)S(48)O(188)(H(2)O)(12)(CH(3)COO)(24) 已通过单晶 X 射线晶体学和 (1)H NMR、IR、拉曼和 UV-vis 光谱进行了制备和表征。固态结构揭示了一种前所未有的有趣排列，由纳米级阴离子立方体制成。这个{Mo(84)}-型立方盒的惊人开放结构具有一个大的内部空隙，可通过其六个直径约为 9 Å 的开放正方形面进入。重要的是，由于存在 24 个暴露的可交换的醋酸盐配体，这个分子体系似乎具有很高的可功能化性。
