By introducing three pyridyl-1H-tetrazole derivatives to Keggin–Ag-(1,10-phenanthroline) system, five new polyoxometalate-based inorganic–organic hybrid compounds with different dimensionalities and structures, [Ag3(4-ptz)2Na(phen)(HPMo12O40)]·2H2O (1), [Ag4(3-ptz)2(phen)2(HPMo12O40)] (2), [Ag4(3-ptz)2(phen)2(HVW12O40)] (3), [Ag3(3-bptzb)(phen)2(PMo12O40)] (4) and [Ag3(3-bptzb)(phen)2(VW12O40)] (5) (phen = 1,10-phenanthroline, x-ptzH = 5-(x-pyridyl)-1H-tetrazole (x = 3, 4), 3-bptzb = 1,4-bis(5-(3-pyridyl)-tetrazolyl)butane), have been synthesized under hydrothermal conditions. Compound1is a 1-D belt architecture constructed from an Ag-4-ptz metal–organic chain and two Ag–PMo12O40–Na–phen inorganic–organic chains. When 3-ptzH was introduced as secondary ligand in2and3instead of 4-ptzH, two isostructural architectures were obtained, which contain a 1-D zigzag Ag-3-ptz chain with phen ligands hanging on both sides of the chain. The Keggin anions connect adjacent Ag-3-ptz chains to construct 2-D networks. When the flexible 3-bptzb was selected, isostructural4and5with 2-D networks were obtained, which were constructed from binuclear subunits and Keggin–Ag inorganic chains. The influence of three pyridyl-1H-tetrazole derivatives as secondary ligands on the dimensionalities and architectures of1–5was discussed. The electrochemical and photocatalytic properties of the compounds were investigated. [ABSTRACT FROM PUBLISHER]
