The title complex [Zn2(hfipbb)2(2,2′-bpy)2]n 1 has been hydrothermally synthesized from Zn(NO3)2·6H2O, 4,4′-(hexafluoroisopropylidene)bis(benzoic acid) and 2,2′-bipyridine. Single-crystal 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. Crystal data: C54H32F12N4O8Zn2, Mr = 1223.58, monoclinic, space group P21/c, a = 27.557(6), b = 16.751(3), c = 11.350(2), β = 99.21(3)°, V = 5171.5(18)3, Z = 4, Dc = 1.572 g/cm3, F(000) = 2464, μ = 1.030 mm-1, the final R = 0.0552 and wR = 0.1070 for 6631 observed reflections (I > 2σ(I)).
