【Abstract】 A new Keggin type supramolecular compound,[( L1)( H4 Si Mo12O40) ]·8H2O( 1),has been synthesized under hydrothermal conditions and structurally characterized by IR spectrum and single crystal X-ray diffraction. C3H30Mo12N2O48 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 Si Mo12O40and L1 molecules,then two components are connected by the hydrogen bonding interactions into one- dimensional ribbon supramolecular chain. Moreover,the electrochemical behavior and the electrocatalytic property toward NO2-reduction of the title compound modified carbon paste electrode( 1- CPE) was studied by cyclic voltammetry.
