| Abstract: | A new bicapped Keggin molybdenum-vanadium polyoxometalate Cu(2,2'-bpy)3]{Cu(2,2'-bpy)2]2HPⅤMo8VIV6IVO42}}·2H2O 1(bpy=bipyridien) was prepared under hydrothermal conditions, and characterized by elemental analysis, IR, X-ray photoelectron spectroscopy, powder and single crystal X-ray diffraction analysis. The compound 1 crystallized in a monoclinic system, with a C2/c space group:a=2.8734(3) nm, b=1.47333(12) nm, c=2.31023(16) nm, β=112.509(5)°, V=9.0351(12) nm3, Z=1, R1=0.0489, wR2=0.1286. The polyoxoanion of compound 1 is a bi-capped P/Mo/V Keggin cluster supporting two copper complexes fragment through the oxygen of capping V atoms of polyoxoanion. Compound 1 exhibits an extended three-dimensional supramolecular network via hydrogen-bonding and π-π stacking interactions between polyoxoanion, water molecules and 2,2'-bpy molecules. |
