Three new organic-inorganic hybrid compounds based on copper-bis(triazole) complexes and Keggin-type polyoxometalates (POMs) with different negative charges, [Cu(I)BBTZ](3)[PMo12O40] (1), [Cu(I)BBTZ][Cu(I)(HBBTZ)(2)][SiMo12O40]center dot 2.5H(2)O (2) and [Cu(I)BBTZ](6)[(SiW2W10O40)-W-V-O-VI]center dot 2H(2)O (3) (BBTZ = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene), have been hydrothermally prepared and characterized by elemental analyses, IR spectra, TG analyses, XPS spectra, powder X-ray diffraction and single-crystal X-ray diffraction analyses. Compounds 1 and 2 exhibit the POM-templated 3D host-guest supramolecular frameworks. Compound 3 displays a POM-supported 3D open framework. In these three hybrid compounds, the structural transformation from host-guest framework to open framework were modulated by the introduction of Keggin-type polyoxoanions with different negative charges. Moreover, the electrochemical properties of compounds 1-3 were investigated and all these compounds show the electrocatalytic activities towards the reduction of nitrite.
