In this paper, we report the hydrothermal synthesis and physicochemical characterization of a complicated high-dimensional and high-connected POM-based hybrid compound, namely, [Ag-3(pytz)(2)(H2O)](2).[HAgGeMo12O40]center dot H2O, which has been synthesized by reactions of pyridyltetrazoles and Keggin POMs. X-ray diffraction and crystallographic analyses reveals that the new compound exhibits POMs chains pillaring transition-metal complexes, which represents the highest coordination number of Keggin POMs up to date. Moreover, the new compound bulk-modified carbon-paste electrode (1-CPE) displays good electrocatalytic activity toward the reduction of nitrite, and the result of the photocatalytic activities indicates that the new compound presents better degradation activity and may be a potential photocatalyst to oxidative decomposition of rhodamine B dye in the presence of crystals [Ag-3(pytz)(2)(H2O)](2)center dot[HAgGeMo12O40]center dot H2O catalyst under ultraviolet-light irradiation.
