| 摘 要： | The title complex Zn2（hfipbb）2（2,2′-bpy）2], 1 has been hydrothermally synthesized from Zn（NO3）2·6H2O, 4,4′-（hexafluoroisopropylidene）bis（benzoic acid） and 2,2′-bipyridine. Singlecrystal X-ray analysis reveals that 1 presents a one-dimensional coordination polymer with pseudo-helical chain structure. Two Zn（Ⅱ） atoms in an unsymmetrical unit of 1 adopt distorted octahedral and square-pyramidal coordination geometries, respectively. The packing of parallel chains gives a three-dimensional supramolecular network supported by π-π stacking interactions.
