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(I2σ(I)).1 shows green photoluminescent property at room temperature.
