A novel supramolecular compound based on three kinds of Keggin polyoxoanions PMo₁₂O₄₀^3 ? with different coordination modes [(phen)₄Cu₂(PMo₁₂O₄₀)][(phen)₂Cu (PMo₁₂O₄₀)]₂[PMo₁₂O₄₀][(phen)₂Cu(H₂O)]₂¡¤4H₂O (1), has been hydrothermally prepared and characterized by elemental analysis, IR, TG, XRD and single-crystal X-ray diffraction. Compound 1 is composed of one [(phen)₄Cu₂(PMo₁₂O₄₀)]⁺ cation, two [(phen)₂Cu(PMo₁₂O₄₀)]^? anions, one [PMo₁₂O₄₀]^3 ? anion, two [(phen)₂Cu(H₂O)]^2 + cations and four lattice water molecules, generating an interesting three-dimensional supramolecular framework via supramolecular interactions, in which there are three kinds of Keggin polyoxoanions PMo₁₂O₄₀^3 ? with different coordination modes. To the best of our knowledge, the title compound represents the first example of a structure containing three kinds of Keggin POMs with different coordination modes up to now. Its electrochemical and electrocatalysis behavior have been investigated in detail.
