A novel inorganic-organic hybrid compound based on mixed-valence Wells-Dawson arsenotungstate and mixed-ligand Cu(I) units, Cu{sub 8}{sup I}(imi){sub 4}(bpy){sub 6}(H{sub 2}O)[As{sub 2}{sup V}W{sub 2}{sup V}W{sub 16}{sup Vl}O{sub 62}].2H{sub 2}O (1) (bpy=4,4'-bipydine; imi=imidazole), has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, luminescent spectrum and single crystal X-ray diffraction. Single-crystal X-ray diffraction revealed that four terminal and three bridging oxygen atoms of the Wells-Dawson cluster are coordinated to Cu(I) ions and form an unprecedented hepta-supporting polyoxometalate. The functionalized arsenotungstates are further connected by two kinds of tridentate linkers, Imi-Cu-(bpy)-Cu-(bpy)-Cu-(bpy)-Cu-Imi and Imi-Cu-(bpy)-Cu-(bpy)-Cu-H{sub 2}O, to construct a 3D framework with 4{sup 6}.6{sup 4} topology. The hybrid material has an intense emission at about 397 nm. - Graphical abstract: A novel organic-inorganic hybrid compound based on mixed-valence Wells-Dawson arsenotungstate and mixed-ligand Cu(I) units has been successfully synthesized. The functionalized arsenotungstate exhibits a five-connected 4{sup 6}.6{sup 4} topology network.
