  Using imdazole-2-carboxylic and biimdazole-4,4′-dicarboxylic acid to construct Keggin-based mono-nuclear Ag+ subunit and double Cl-capped tri-nuclear Cu+ clusters

  摘要：

  Three metal-organic complexes (MOCs) based on Keggin-type polyoxometalate anions and two organic ligands 1H-Imdazole-2-carboxylic acid (L-1) and 1H, 1'H-Biimdazole-4,4'-dicarboxylic acid (L-2), [Ag-2(L-1)(4)] [HPMo12O40]center dot 3H(2)O (1), [Ag-2(L-1)(4)][HPW12O40]center dot H2O (2) and [(Cu6Cl4)-Cl-I(L-2)(6)][H3PMo12O40]center dot 2NO(3) (3), have been synthesized under hydrothermal conditions and structurally characterized by single crystal X-ray diffraction analyses, elemental analyses and IR spectra. Complexes 1 and 2 are isostructural and contain a supramolecular chain with a -ABAB- style. The adjacent one dimensional (1D) chains through hydrogen bonding interactions form a 2D supramolecular layer. In complex 3, there exist double Cl-capped tri-nuclear Cu+ clusters. Furthermore, the photocatalytic and fluorescent properties of complexes 1-3 and electrochemical behavior of complexes 2 and 3 were investigated. (C) 2015 Elsevier B.V. All rights reserved.
