A 3D inorganic-organic hybrid constructed from Strandberg-type polyoxometalates and silver complexes: Synthesis, structure and properties

A 3D Strandberg-type polyoxometalate-based inorganic-organic hybrid, [Ag4(H3L)2(P2Mo5O23)]·H2O (1) (H2L = 2,6-dimethyl-3,5-bis(pyrazol-3-yl)pyridine), has been synthesized under hydrothermal conditions and structurally characterized by single crystal X-ray diffraction, elemental analysis, IR, TG and powder X-ray diffraction. In compound 1, the adjacent [P2Mo5O23]6− clusters are linked by Ag1 into a 2D layer with left- and right-handed helical chains. And the layers are further linked together through organic ligands H2L and Ag⋯Ag interactions into a 3D framework with 1D channels extended along c axis. The luminescence, electrochemical properties and photocatalytic activities of compound 1 have also been investigated.
