Abstract: A new compound, (C6H6N3)7(PMo12O40)(PMoMo11O40)·2CH3CH2OH·5H2O, was synthesized and characterized by means of elemental analyses, IR spectroscopy, 1H NMR spectroscopy and single crystal X-ray diffraction. This is the first example of benzotriazole-polyoxometalates species. The compound crystallized in a triclinic space group P1 with a=1.8378(4) nm, b=1.9078(4) nm, c=2.1037 (4) nm, α=63.41(3)°, β=64.31(3)°, γ=68.38(3)°, V=5.803(2) nm3, Z=2, R1=0.0486, wR2=0.1357. The X-ray crystallographic study showed that the crystal structure was constructed by electrostatic interactions and hydrogen bonds between dodecamolybdophosphorate anions and protonated benzotriazole cations. The electrochemical behavior and the reduction of nitrite and hydrogen peroxide electrocatalyzed by the title compound were studied.
