| 摘 要： | A novel hybrid tungstocuprate(Ⅱ) Cu(2,2′-bpy)3]2H4CuW12O40]·6H2O(2,2′-bpy=2,2′-bipyridine) was synthesized via hydrothermal method and characterized using elemental analyses, IR, UV, XPS, TG-DSC, EPR, and X-ray single crystal diffraction. The structural analysis shows that the complex consists of an unusual Keggin-type polyoxoanion CuW12O40]6- and a pair of chiral complex cations Cu(2,2′-bpy)3] together with four protons and six crystallization water molecules, and the Keggin polyoxoanion is connected with Cu(2,2′-bpy)3] via multiple C—H…O hydrogen bonds resulting in a dimer. |
