A new inorganic?organic hybrid compound based on polyoxometalates was synthesized by hydrothermal method，and characterized by X-ray single crystal diffraction，fourier transform infrared spectroscopy（IR），thermal analysis test（TG），X-ray diffraction analysis（XRD），scanning electron microscopy（SEM），element analysis.The X-ray single crystal diffraction analysis result showed that the structural formula of the compound was（PMo12O40）［Cu6（C2H4N4）6］ （PMo12O40）?H2O（short for Cu-3-trz-PMo12），which was belonged to trigonal crystal system and R-3 space group.The crystal cell parameters were a=1.756 66（3） nm，b=1.756 66（3） nm，c=2.303 24（6） nm，α=β=90°，γ=120°，V=6.155 2（3） nm3，Z=3，R1=0.023 8，wR2=0.059 2.The compound was a dimer composed of six 3-amino-1，2，4-triazoles，six copper ions，two classical Keggin type［PMo12O40］3- and one interstitial water molecule.The two dimers were alternately linked by hydrogen bonds to form secondary units，and each secondary unit was formed by hydrogen bonds to form a three?dimensional supramolecular structure.The results showed that the heterogeneous catalyst had good catalytic activity and stable repeatability in the process oxidation of iodide ion by hydrogen peroxide.
