An inorganic-organic hybrid material based on Dawson polyoxometalates, [Na-2 {Cu-2(I) (bim)(2)}(2) (P2W18O62)]center dot 2H(2)O (bim = biimidazole) (1), has been hydrothermally synthesized and fully characterized. In 1, each {P2W18} cluster as a hexa-node ligand connects to six adjacent Dawson clusters via six Na1 ions to generate a pure inorganic 2-D layer, further joined by bimetal-organic segments [Cu-2(bim)(2)](2+) to form a 3-D inorganic-organic hybrid framework with channels. The structure can be simplified to 3,8-connected 3-D networks with (4(3))(4(18)center dot 6(24)center dot 8(3)) topology, which shows bifunctional electrocatalytic performance for oxidation of ascorbic acid (AA) and reduction of nitrite (NO2-), and high-efficient degradation ability for three typical dyes under UV light irradiation.
