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.展开更多
