Popis: | Two inorganic–organic hybrid supramolecular compounds based on polyoxometalates formulated as (C4H8NH2)4[Mo8O26] (1) and (NH4)Na2[AsIIIMo6O21(O2CCH2NH3)3]·8H2O (2) have been synthesized by conventional solution method and characterized by infrared, UV–Vis and single-crystal X-ray diffraction analyses. Thermal analysis was performed to study their thermal stability. The atomic arrangement in compound (1) can be described as inorganic layers built by [Mo8O26]4−, pyrrolidinium cations are embedded into layers. The fascinating structural feature of compound (2) is that the glycine molecules are bounded to two edge-sharing Mo centers via their carboxylate functionality leading to functionalized heteropolymolybdate [AsIIIMo6O21(O2CCH2NH3)3]3−, extensive net hydrogen bonds between cations and anions contribute to the crystal packing. The electrochemical behavior of compound (2) has been studied. |
