Synthesis and Structure of a New Coordination Polymer [Cd(pzdc)(bpy)]n (H2pzdc = Pyrazine-2,3-dicarboxylic Acid, bpy = 2,2′-Bipyridine)

Abstract

A new 3D coordination polymer, [Cd(pzdc)(bpy)]n (1) (pzdc = pyrazine-2,3-dicarboxylic acid, bpy = 2,2′-bipyridine), has been hydrothermally synthesized and characterized by the elemental analyses, IR spectrum and single crystal X-ray diffraction. X-ray diffraction analysis reveals that 1 (C16H10CdN4O4) crystallizes in monoclinic space group P21/c, features an interesting 3D zipper-like networks constructed by 2D layers via strong π–π packing interactions. Cell unit parameter for 1: a = 9.767(1), b = 14.022(2), c = 13.719(2) A, β = 100.86(1)o, and Z = 4.
