Synthesis And Characterization And Crystal Structures Of The Complexes With Aniline-2,5-disulfonic Acid

During the past decade, the synthesis and investigation of polymer consisting of aromatic acids and transition metals have is drawing more and more attention of professionals in the field. Especially due to their potential applications in diverse areas such as conductance, abruption, absorption, catalysis and so on. So far, the most research of polymer are about aromatic polycarboxylates and aromatic phosphide. In stark contrast, for the organosulfonate (RSO3-) anions show weak coordination strength with transitional metals in aqueous solution, they were regarded as“poor ligands”. So, there has been relatively little research conducted on the coordination properties of sulfonate polymer.In this thesis, we try to synthesize novel coordination complexes by the use of Aniline-2,5-disulfonic acid monosodium salt as reactant assembling with metal ions through coordinative bonds or supramolecular weak interactions while we used 4,4’-bipyridyl and1,4-bis((1H-imidazol-1-yl)methyl)benzene as N-donor. Three novel complexes were synthesized, and the crystal structures have been determined by X-ray diffraction method, which have been confirmed by IR.The main contents of the thesis are as following:1. The research and the development of the metal sulfonate complexes were summarized.2. Two new complexes were synthesized from NaHL by using hydrothermal method, and determined their structures by single-crystal X-ray diffraction. 3. Another complex has been synthesize by use NaHL as the organic ligand and Zn salt as central ions. This complex has been determined by single-crystal X-ray diffraction.
