摘要

A novel 3D heterometal-organic coordination polymer [{K-2(H2O)(6)}{Cu-3(Hpimdc)(2)(CN)(2)}{Cu-2(H(3)pimdc)(2)(CN)}]center dot 2H(2)O (1) (H(3)pimdc = 2-propyl-IH-imidazole-4,5-dicarboxylic acid) has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, PXRD, UV-vis, and single-crystal X-ray diffraction. In complex 1, adjacent K+ ions are linked through H(3)pimdc to form binuclear chain units {K-2(H2O)(6)}(n), which connect with unique Cu-cyanide complex linker {Cu-3(CN)(2)(Hpimdc)(2)} to form 2D layers. The 2D layers are further connected via another linkage unit {Cu-2(CN)(H(3)pimdc)(2)} to form 3D frameworks with (4(1)16(2))(2)(3(3)4(2)5(1)10(1)12(3)16(4)) topology. The H(3)pimdc ligand in 1 exhibits mu(2)- and mu(4)-two kinds of coordination fashions. In addition, the N-2 adsorption, fluorescence, and photocatalytic properties of polymer 1 are evaluated detailed.
