| Abstract: | Two new one-dimensional zigzag chain coordination polymers, Co(hfipbb)(2,2'- bpy)(H2O)2]n 1 and Co(hfipbb)(1,10-phen)(H2O)]n 2, have been synthesized under hydrother- mal reactions from CoCl2.6H2O, 4,4'-(hexafluoroisopropylidene)bis(benzoic acid) and 2,2'-bipyridine or 1,10-phenanthroline ligands, respectively. Single-crystal X-ray analyses revealed that the zigzag chains of 1 and 2 are linked into three-dimensional supramolecular networks by both O-H…O hydrogen-bonds and π…πstacking interactions. Crystal data for 1: C27H20CoF6N2O6,Mr=641.38, orthorhombic, space group Pnna, a = 9.3820(19), b = 27.366(6), c = 10.106(2) (A), V = 2594.8(9) (A)3, Z = 4, Dc = 1.642 g/cm3, F(000) = 1300, μ = 0.752 mm-1, R = 0.0311 and wR = 0.0924. Crystal data for 2: C29H18CoF6N2O5, Mr = 647.38, monoclinic, space group P21/n, a = 7.7626(16), b = 29.446(6), c = 11.281(2) (A),β= 93.98(3)°, V = 2572.3(9) (A)3, Z = 4, Dc = 1.672 g/cm3, F(000) = 1308, μ= 0.757 mm-1, R = 0.0403 and wR = 0.0820. |
