摘要：
A new 2D coordination polymer, [Cd-2(pzdc)(2)(4,4'-bpy)(H2O)(2)](n) (1) (pzdc = pyrazine-2,3-dicarboxylic acid, 4,4'-bpy = 4,4'-bipyridine), has been hydrothermally synthesized and characterized by elemental analyses, IR spectra and single crystal X-ray diffraction. X-ray diffraction analysis reveals that 1 features an interesting 2D stair-like layer with linear [Cd-2(pzdc)(2)(H2O)(2)](n) ribbons linked by 4,4'-bpy bridges. Furthermore, these layers are packed in an ABAB arrangement to give a 3D supramolecular network via hydrogen bonding and pi-pi packing interactions. Compound 1 displays strong fluorescent emission in the solid state at room temperature.
