| Abstract: | A novel metal coordination polymer [Ni(TB)2(H2O)2]n·2H2O (H3TB=1,3,5-tris (carboxymethoxyl)benzene) was constructed under solvothermal conditions, with 1,3,5-tris(carboxymethoxyl)benzene as the directional ligand, reacted with nickel acetate. The structure of polymer was characterized by elemental analysis, IR and X-ray single crystal diffraction. The thermal stability, fluorescence properties and Hirshfeld surface forces were also studied. Single crystal structure analysis show that, the crystal system and space group of the complex is triclinic and $P overline{1}$. The central ion Ni(Ⅱ) of the complex is six coordinated by with O atoms of carboxylic acid from four different 1,3,5-tris(carboxymethoxyl)benzene ligands, O atoms of two water molecules to give a octahedral geometry NiO6. A one-dimensional chain configuration with holes is formed by the coordination of oxygen atom with 1,3,5-tris (methoxycarboxyl) benzene. The fluorescence and TG results show that the complex have good fluorescence properties and thermal stability. Hirshfeld surface analysis results reveal that the O…H/H…O interactions is 39.0% contribution to the total Hirshfeld surface of the complex molecules, while H…H and O…O interactions is 25.9% and 13.6%, respectively. |
