Abstract：Under hydrothermal conditions two supramolecular compounds based on Keggin and flexible bis (Tetrazol-pyridine) ligands have been synthesized, [La1.5PMo12O40] (1) (La=1,1'-(1,4-butanediyl)bis (3-(2H-Tetrazol-5-yl) -pyridine)) and [Lb2SiMo12O40] (2) (Lb =1,1'-(1,3-propane)bis(3-(2H-Tetrazol-5-yl) -pyridine)) characterized by single -crystal X -ray diffraction, elemental analyses and IR spectra.Structural analysis shows that compound 1 crystallizes in space group P 1, a=13.575(5)?,b=14.060(5)?,c=15.754(5)?,α=73.136(5) °,β=80.084(5) °,γ=73.048(5)°,V=2739.9(17)?3,Z=2,R1 =0.0529,ωR2 =0.1407.Compound 2 crystallizes in space group Cmca , a=23.392(5)?,b=0.451 (5)?,c=25.013(5)?,V=6115(3)?3 ,Z=4,R1 =0.0395,ωR2 =0.0923.In these two compounds , the Keg-gin polyoxoanions and bis ( Tetrazol-pyridine ) ligands La and Lb link each other through hydrogen bonding in-teractions to construct supramolecular networks .We studied the electrochemical and photocatalytic properties of 1 and 2 .
