摘要：
The title complex [Zn-2(hfipbb)(2)(2,2 '-bPY)(2)](n) 1 has been hydrothermally synthesized from Zn(NO3)(2)center dot 6H(2)O, 4,4'-(hexafluoroisopropylidene)bis(berizoic 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 pi ... pi stacking interactions. Crystal data: C54H32F12N4O8Zn2, M-r = 1223.58, monoclinic, space group P2(1)/c, a = 27.557(6), b = 16.751(3), c = 11.350(2) angstrom, beta = 99.21(3)degrees, V= 5171.5(18) angstrom(3), Z = 4, D-c = 1.572 g/cm(3), F(000) = 2464, mu = 1.030 mm(-1), the final R = 0.0552 and wR = 0.1070 for 6631 observed reflections (I > 2 sigma(I)).
