摘　　要：A new decatungstate incorporated metal-organic framework {[Co2（bpdo）5（H2O）n- W10O32]}n·nbpdo·2nH2O（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.A new decatungstate incorporated metal-organic framework {[Co2（bpdo）5（H2O）n- W10O32]}n·nbpdo·2nH2O（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.
