摘　　要：A new purely inorganic 2D framework, {PMo12040Bi2（H20）2}·4H20（1）, was synthesized under solvo- thermal condition and characterized by infrared（IR） spectroscopy, thermal gravimetric analysis, UV-Vis spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction. Structural analysis reveals that compound 1 consists of Keggin unit {PMo12O40} with two bismuth atoms capping two opposite pits, leading to the bi-bismuth-capping Keggin polyoxometalate. Compound 1 not only displays excellent photodegradation activity for methyl orange（MO）, but also has a high absorption capacity for rhodamine B（RhB） and methylene blue（MB）. Moreover, compound 1 is extremely stable and easily separated from the reaction system for reuse.A new purely inorganic 2D framework, {PMo12040Bi2（H20）2}·4H20（1）, was synthesized under solvo- thermal condition and characterized by infrared（IR） spectroscopy, thermal gravimetric analysis, UV-Vis spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction.
