Three supramolecular compounds based on [P2Mo5O23](6-) and Ni(II)-bim, [Ni(bim)(3)](3)[P2Mo5O23]2H(2)O (1), [Ni(Hbim)(bim)(2)](4)[P2Mo5O23](2)3H(2)O (2), and [Ni(bim)(Hbim)(phen)](2)[P2Mo5O23]7H(2)O (3) (bim=2,2-biimidazole, phen=1,10-phenanthroline), have been synthesized under hydrothermal conditions and characterized by elemental analysis, single-crystal X-ray diffraction, IR, and TG. All the compounds show 3-D supramolecular networks constructed from weak interactions among free Ni(II) complex, water, and oxygens of [P2Mo5O23](6-). Compound 3 represents the first supramolecular example integrating {Ni(bim)(Hbim)(phen)} with Strandberg-type phosphomolybdate. The compounds display good electrocatalytic activity to reduce hydrogen peroxide and intense fluorescence properties in solution at room temperature.
