据报道，超分子主客体循环结构的形成是通过硫酸根和磺酸根阴离子驱动的[Mo2O2S2]2+硫代阳离子的自缩合过程而形成的。通过X射线衍射对配合物[(SO4)2Mo10O10S10(OH)10(H2O)5]4–和[(EtSO3)2Mo10O10S10(OH)10(H2O)5]2–进行固态表征，并特别关注氢键相互作用的分析，这确保了此类结构的主客体稳定性。考虑到这些特性，我们报告了氧硫代钼环状材料接枝到磺化树脂（例如 Dowex 50-80）上的初步结果。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, 德国, 2009)
The formation of supramolecular host–guest cyclic architectures, built up through the self-condensation process of [Mo2O2S2]2+ oxothiocations driven by sulfate and sulfonate anions is reported. The complexes [(SO4)2Mo10O10S10(OH)10(H2O)5]4– and [(EtSO3)2Mo10O10S10(OH)10(H2O)5]2– were characterized in the solid state by X-ray diffraction, and particular attention was given to the analysis of the hydrogen-bonding interactions, which ensure the host–guest stability of such architectures. Taking into account these properties, we report preliminary results on the grafting of oxothiomolybdenum cyclic materials onto sulfonated resin such as Dowex 50–80. (© Wiley-VCH Verlag GmbH & Co.
