A new decatungstate incorporated metal-organic framework {Co-2(bpdo)(5)(H2O)(4)-W10O32]}(n)center dot nbpdo center dot 2nH(2)O (1, bpdo = 4,4'-bis(pyridine-N-oxide) has been synthesized through a one-step hydrothermal reaction and characterized by elemental analyses, IR. solid UV-vis absorption spectra, and single-crystal X-ray diffraction. The structural analysis indicates that 1 displays a one-dimensional ladder structure with [W10O32](4-) as guest incorporated by electrostatic interaction. The photocatalytic property of the framework toward a rhodamine B (RhB) solution was also investigated. The results indicated that compound 1 possesses high photocatalytic activity in heterogeneous system under sunlight irradiated.
