A novel organic-inorganic hybrid compound H-2[Cu-2(bpy)(2)(H2O)2(mu-nx)](2)[H2W12O40]center dot 9H(2)O (1) (2,2'-bipyrine and ox = oxalate) has been successfully synthesized under open-air mild reaction condition and characterized by elemental analysis, IR spectrum, thermal stability analysis, single-crystal X-ray diffraction and magnetic susceptibility measurement. The main structural feature of compound 1 is the presence of alpha-metatungstate cluster [H2W12O40](6-) as inorganic building blocks, on which the bridged-oxalate dinuclear copper metalorganic units are supported. Magnetic susceptibility studies reveal that the compound 1 shows paramagnetic property with a magnetic moment about the Cu2+ ion, indicating antiferromagnetic coupling between the neighboring Cu2+ ions in the structure. The compound 1 also displays a good catalytic activity with the conversion 42.4% for H2O2 decomposition.
