摘要
A metal-organic coordination compound formulated as [Cd(pzdc)(2,2’-bipy)]n·nH2O 1 (H2pzdc = pyrazine-2,3-dicarboxylic acid, 2,2’-bipy = 2,2’-bipyridine) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, TG, fluorescence spectrum and single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21/c with a = 10.8081(13), b = 14.4328(17), c = 10.2530(12) , β = 98.504(2)o, V = 1581.8(3) 3, C16H14CdN4O5, Mr = 454.71, Dc = 1.909 g/cm3, μ(MoKα) = 1.420 mm-1, F(000) = 904, Z = 4, the final R = 0.0230 and wR = 0.0554 for 2901 observed reflections (I > 2σ(I)). It exhibits an interesting two-dimensional network structure and shows yellow photoluminescent property at room temperature.
