The formation of supramolecular host–guest cyclic architectures, built up through the self‐condensation process of [Mo 2 O 2 S 2 ] 2+ oxothiocations driven by sulfate and sulfonate anions is reported. The complexes [(SO 4 ) 2 Mo 10 O 10 S 10 (OH) 10 (H 2 O) 5 ] 4– and [(EtSO 3 ) 2 Mo 10 O 10 S 10 (OH) 10 (H 2 O) 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.
