摘要
Two new polyoxometalate（POM）-based hybrid compounds, [Cu（en）][H4Mo4O16]0.5（1）（en=ethylenediamine） and [Ag（3-CsH6N2）2][H2PMo12O40]（2）（3-C5H6N2=3-aminopyridine）, containing different transition metal- amine subunits were hydrothermally synthesized and characterized by elemental analyses, infrared spectroscopy and single-crystal X-ray diffraction. For compound 1, each [H4Mo4O16]4-（M04O16） cluster was linked to four neighboring Mo4O16 clusters through four [Cu（en）]2＋ subunits to yield a （2,4）-connected 2D layer, which was further extended to a 3D supramolecular network via hydrogen bonding interactions. For compound 2, the adjacent [H2PMo12O40]- clusters were bridged by [Ag（3-C5H6N2）2]＋ subunits to generate a 1D chain. The electrochemical behaviors and the photoca- talytic activities of compounds 1 and 2 were studied in detail.
