A novel one-dimensional chain complex [Zn(dafo)2(H2O)2](NO3)2 was synthesized. It has been characterized by IR, UV, TGA, Elemental analysis and X-ray diffraction analysis. The crystal belongs to triclinic system, P1 space group. The Crystallographic data are: a = 0.702 7(14) nm, b = 0.828 95(17) nm, c = 10.225(2) nm, α = 95.02(3)°, β = 91.45(3)°, γ = 99.85(3)°. The crystal structure data indicate that the Zn(Ⅱ) ion was coordinated with the four nitrogen atoms of two dafo and two oxygen atoms of two coordination water molecules, respectively. The complex has a one-dimensional chain structure, which is formed by hydrogen bonds.
用水杨酸和吡啶与Ni(ClO4)26H2O 合成了一个新颖配位聚合物[Ni(Hsal)2(Py)2]n。对配合物进行了X射线衍射结构表征, C24H20N2NiO6, Mr = 491.13, 晶体属三斜晶系, P 空间群, 晶胞参数: a = 7.372(2), b =10.852(2), c = 14.728(3) ? a = 108.36(3), b = 93.83(3), g = 103.67(3), V = 1073.7(4) ?。F(000) = 508, m = 0.949mm-1, Z = 2, Dc = 1.519 g/cm3。最后修正到R = 0.0390, wR = 0.0772。配合物中Ni为五配位, 呈四方锥构型。配合物中2个水杨酸根的配位方式不一样, 其中一个水杨酸根作为双齿桥连配体, 使配合物呈一维链状结构。水杨酸苯环的-堆积作用和分子间的氢键作用, 又使配合物呈二维网络结构。
