A novel monosubstituted Keggin-type polyoxometalate (POM)-based metal-organic framework [(Cu4V2I)-V-II(pzca)(6)(HPCuMo11O39)(H2O)(6)]center dot 2H(2)O (1) (Pzca = 2-pyrazinecarboxylic acid) has been hydrothermally synthesized and characterized by IR, elemental analysis, TGA and single crystal X-ray diffraction analysis. Compound 1 shows a (2,3,4,7)-connected three-dimensional framework with {4 . 6(2) . 9 . 10(2)}{4 . 9(2)} {4(2) . 6(9) . 8(7) . 10(3)}{6 . 9 . 10}(2){9}(2) topology, which is constructed from the monosubstituted Keggin chains [HPCuMo11O39](n)(4n-) and metal-carboxylate chains [Cu-6(pzca)(6)](n)(4n+). The electrochemical behavior and photocatalytic activity of compound 1 have been investigated.
