| description | The development of hybrid materials based on polyoxometalates constitutes a strategy for the design of multifunctional materials. The slow evaporation of an aqueous solution of [NaP<sub>5</sub>W<sub>30</sub>O<sub>110</sub>]<sup>14−</sup> in the presence of γ-Cyclodextrin (γ-CD) led to the crystallization of a K<sub>6</sub>Na<sub>8</sub>{[NaP<sub>5</sub>W<sub>30</sub>O<sub>110</sub>]•(C<sub>48</sub>H<sub>80</sub>O<sub>40</sub>)}•23H<sub>2</sub>O (<b>NaP<sub>5</sub>W<sub>30</sub></b><b>•1CD</b>) supramolecular compound, which was characterized by single-crystal X-ray diffraction, IR-spectroscopy, thermogravimetric and elemental analyses. Structural analysis revealed the formation of 1:1 {[NaP<sub>5</sub>W<sub>30</sub>O<sub>110</sub>]•[γ-CD]}<sup>14−</sup> adduct in the solid state. Studies in solution by cyclic voltammetry, electrochemical impedance spectroscopy, <sup>1</sup>H NMR spectroscopy, and <sup>31</sup>P DOSY, have demonstrated weak interactions between the inorganic anion and the macrocyclic organic molecule. |
