A new Keggin type supramolecular compound, [(L1)(H4SiMo12O40)]· 8H2O (1), has been synthesized under hydrothermal conditions and structurally characterized by IR spectrum and single crystal X-ray diffraction.C3 H30 Mo12 N2 O48 Si, triclinic, P1 a=12.8900(6)?, b=13.3870(6)?, c=13.5260(6)?,α=87.0260(10)°,β=88.6050(10)°,γ=88.2740(10)°,Z=2,V=2329.22(18) ?3,Mr=2041.64,Dc=2.888 g/cm3, F(000)=1896,μ=3.259 mm-1 ,S=1.077,R=0.0504,wR=0.1513.Single-crystal X-ray analysis reveals that compound 1 is constructed by the discrete H4 SiMo12 O40 and L1 molecules, then two components are connected by the hydrogen bonding interactions into one-dimensional ribbon supramolecular chain.Moreover, the electro-chemical behavior and the electrocatalytic property toward NO2 -reduction of the title compound modified carbon paste electrode (1-CPE) was studied by cyclic voltammetry.CCDC:1040790.
