| 摘 要： | A metal-organic coordination polymer Cd(bpy)(BDC)]n·nbpy (bpy = 2,2'-bipyri- dine, H2BDC = terephthalic acid) has been hydrothermally synthesized and structurally characteri- zed by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The complex crystallizes in monoclinic, space group C2/c with a = 15.723(5), b = 21.695(5), c = 7.576(5)(A), β = 116.171(7)o, V = 2319.3(18)(A)3, C28H20CdN4O4, Mr = 588.88, Dc = 1.686 g/cm3, μ(MoKα) = 0.987 mm(1, F(000) = 1184, Z = 4, the final R = 0.0464 and wR = 0.0831 for 1882 observed reflections (Ⅰ ＞ 2σI)). It exhibits a three-dimensional network with channels constructed from one-dimensional coordination chains via C-H…O hydrogen bonds and significant aromatic π-π stacking interactions.
