摘要:
A metal-organic coordination compound formulated as [Zn(pzdc)(phen)]n·nH2O 1 (H2pzdc = pyrazine-2,3-dicarboxylic acid, phen = 1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21/n with a = 11.607(2), b = 11.719(2), c = 13.140(3) , β = 110.707(3)o, V = 1671.9(6) 3, C18H12ZnN4O5, Mr = 429.69, Dc = 1.707 g/cm3, μ(MoKα) = 1.511 mm?1, F(000) = 872, Z = 4, the final R = 0.0356 and wR = 0.0853 for 2713 observed reflections (I > 2σ(I)). It exhibits an interesting two-dimensional layer structure and shows yellow photoluminescent property at room temperature.
