A new compound, (C 6H 6N 3) 7(PMo Ⅵ 12 O 40 )(PMo ⅤMo Ⅵ 11 O 40 )·2CH 3CH 2OH·5H 2O, was synthesized and characterized by means of elemental analyses, IR spectroscopy, 1H N...A new compound, (C 6H 6N 3) 7(PMo Ⅵ 12 O 40 )(PMo ⅤMo Ⅵ 11 O 40 )·2CH 3CH 2OH·5H 2O, 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 P 1 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) nm 3, Z =2, R 1=0 0486, wR 2=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.展开更多

The compound crystallized in a triclinic system with a space group P 1 and a =1.3108(3) nm, b =1.3515(3) nm,c =1.3870(3) nm, V =2.0217(7) nm 3,Z =1,R _1=0.0391,wR _2=0.0959. The structure unit of the complex was constructed from [HPW_ 12 ·O_ 40 ] -,(C_5H_6N_5) + and C_3H_7NO,which further extends to form a novel three-dimensional host-guest network via hydrogen-bonding interactions. The anti-tumor activity of the compound was examined in two human tumor cell lines in vitro .展开更多
