The title complex [Zn2(hfipbb)2(2,2'-bpy)2]n 1 has been hydrothermally synthesized 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 aoopt distorted octahedrai and square-pyramidal coordination geometries, respectively, The packing of parallel Crystal data: C54H32F12N4O8Zn2, Mr = 1223.58, monoclinic, space group P21/c, a = 27.557(6), b =16.751(3), c = 11.350(2) (A°), β= 99.21(3)°, V= 5171.5(18) (A°)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)).
