| 摘 要： | A new metal-organic coordination polymer Co(2-pya)2(4,4'-bipy)]2n·(4,4'- bipy)0.5· H2O]2n(2-pya = 2-pyridinecarboxylic acid, 4,4'-bipy = 4,4'-bipyridine) 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The complex crystallizes in tetragonal, space group I41/a with a = b = 22.719(2), c = 10.710(2) A, V = 5527.8(14) A3, C54H46N10Co2O10, Mr = 1112.87, Dc = 1.337 g/cm3,μ(MoKα) = 0.665 mm-1, F(000) = 2296, Z = 4, the final R = 0.0633 and wR = 0.1096 for 1261 observed reflections (I ＞ 2σ(I)). It exhibits a one-dimensional chain-like structure constructed by mixed ligands of 2-pyridinedicarboxylic acid and 4,4'-bipyridine.
