Hydrothermal reaction between 1,4-phenylenediacetic acid(H2PDA) and Zn(NO3)2·6H2O at the presence of the second ligand of 1,2-bis((1H-imidazol-1-yl) methyl)benzene(obix) yields a new 2D metal-organic coordination...Hydrothermal reaction between 1,4-phenylenediacetic acid(H2PDA) and Zn(NO3)2·6H2O at the presence of the second ligand of 1,2-bis((1H-imidazol-1-yl) methyl)benzene(obix) yields a new 2D metal-organic coordination polymer [Zn(PDA)(obix)](1),which has been characterized by single-crystal X-ray diffraction,elemental analysis,IR spectroscopy and thermal analysis.Complex 1 presents a two-dimensional(2D) sheet structure and displays strong luminescent emission at room temperature.CCDC:716984.展开更多
A novel cobalt（II） coordination polymer,[Co（BTEC）1/2]n 1,has been synthesized with Co（NO3）2·6H2O and 1,2,4,5-benzenetetracarboxylic acid （H4BTEC） by the hydrothermal method,and characterized by elemental ...A novel cobalt（II） coordination polymer,[Co（BTEC）1/2]n 1,has been synthesized with Co（NO3）2·6H2O and 1,2,4,5-benzenetetracarboxylic acid （H4BTEC） by the hydrothermal method,and characterized by elemental analysis,IR and single-crystal X-ray diffraction. Crystallographic data for 1： C5HO4Co,Mr = 183.99,monoclinic,space group C2/c,a = 16.619（6）,b = 7.416（3）,c = 8.040（3）A,β = 90.612（4）°,V = 990.8（6） A^3,Z = 8,Dc = 2.467 g/cm^3,μ = 3.390 mm^-1,F（000） = 720,R = 0.0307 and wR = 0.0847 for 912 observed reflections （I 〉 2σ（I））. X-ray crystal structural analysis revealed that each Co（II） adopts a tetrahedral coordination mode to link four separate BTEC ligands via uniform monodentate carboxylate groups and each BTEC ligand possesses an 8-connected geometry to connect eight Co（II） ions. Complex 1 exhibits a rare （4,8）-connected net with （45.6）2（410.614.84） topology.展开更多
