| Abstract: | Hydrothermal reactions of K4Fe(CN)6]?3H2O with H2bimdc (H2bimdc = benzimidazole-5,6-dicarboxylic acid) afforded a coordination polymer (CP), Cu(CN)(bimdca)] (1) (bimdca = benzimidazole-5,6-dicarboxylic anhydride), as the first example of the {CuCN}-based CP modified by anhydride. The polymer is characterized by elemental analysis, IR, TG, XRD, and single-crystal X-ray diffraction. In 1, horizontal and vertical parallel chains based on {Cu2(CN)4(bimdca)2} dimer units crisscross resulting in a 2-D network with a (4462) topology, which is further connected to adjacent 2-D layers generating a 3-D supramolecular framework through intermolecular force between oxygens of anhydride. In addition, 1 exhibits interesting fluorescence and good degradation ability for MB under UV light. |
