Three inorganic-organic hybrid complexes, [Cu(Hbiim)(OH)](SiWO)·2HO ( 1), [Cu(Hbiim)](SiWO)·2HO ( 2) and [Ag(Hbiim)](SiWO)·2HO ( 3) (Hbiim = 2, 2′-biimidazole), have been synthesized under hydrothermal conditions, and characterized by elemental analysis, IR, PXRD, TG and single-crystal X-ray diffraction. The crystallographic analysis reveals that in compounds 1- 3, the Keggin polyanions [ α-SiWO] act as inorganic building blocks, which are linked with the dinuclear metal-organic units via Cu-O bonds in compound 1, or through supramolecular interactions in compounds 2 and 3. Compound 1 shows a 3D supramolecular structure constructed by net-like layers. Compounds 2 and 3 display 2D layer structures which were composed of wave-like chains. In addition, these compounds show electrochemical activities, and photoluminescence properties are measured in the solid state. [ABSTRACT FROM AUTHOR]
