摘要：
A novel Wells-Dawson polyoxometalate (POM)-based metal-organic framework (MOF) constructed from bi(triazole) ligand and azo anion, namely, [Ag-13(L)(6)(N-2)(HP2W18O62)] (1) (HL = 4-(1 H-1,2,4-triazol-3-yl)-2 H-1,2,4-triazolyl) has been synthesized under hydrothermal conditions and characterized by single-crystal Xray diffraction, IR spectra, PXRD analysis. In compound 1, the rigid bi(triazole) ligands connected Ag-I ions to construct a 2D metal-organic layer, which was further extended by azo anions forming a 3D framework. The Wells-Dawson type [P2W18O62](6-) anion as a multidentate inorganic ligand coordinated with the Ag-I ions, consolidating the 3D MOF. The L ligands and azo anions were in-situ transformed from a bi(triazole) derivative, which has never been observed in previous reports. In addition, the electrocatalytic and photocatalytic properties of compound 1 have been investigated. (C) 2015 Elsevier B.V. All rights reserved.
