| Abstract: A metal-organic coordination polymer [Zn2(pzdc)(im)3]n (H2pzdc=pyrazine-2,3-dicarboxylic acid, im=imidazole) 1 has been hydrothermally synthesized and characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. Pale yellow crystals crystallize in the monoclinic system, space group P21/c, a=1.364 87(15) nm, b=1.389 43(15) nm, c=0.956 89(10) nm, β=102.354(2)°, V=1.772 6(3) nm3, C15H12N8O4Zn2, Mr=499.07, Dc=1.870 g·cm-3, F(000)=1 000, Z=4, μ(Mo Kα)=2.750 mm-1, the final R=0.032 2 and wR=0.087 8 for 3 208 observed reflections (I>2σ(I)). 1 shows green photoluminescent property at room tempera-ture. CCDC: 775846. |
