Synthesis, Crystal Structure And Properties Of Diverse Ag(I) Supramolecular Complexes With2-sulfoterephthalic Acid

Metal–organic frameworks （MOFs）, possessing the advantages oforganic and inorganic metal ions, have potential applications in variousfields, including photochemistry electrical conductivity molecularmagnetism. This work mainly describes the synthesis，crystal structuresand properties of Ag（I） supramolecular complexes with2-sulfotereph-thalic acid and different N-donor ligands. Full text includes fourchapters:In Chapter1, we primitively introduced the research series ofcomplexes constusted from sulfonic and carboxylic acid ligandspresently and the application of Ag（I） complexes.In Chapter2, Four Ag（1） coordination polymers:{[Ag₂（2-Hstp）（bpy）] H₂O}_n（1）,{[Ag₂（bpy）₂]（2-Hstp）2H₂O}_n（2）,{[Ag（2-stp）（bpy）] [Ag（bpy）][Ag（bpy）]6H₂O}_n（3）,{[Ag（bpy）][Ag（bpy）][Ag（bpy）]（2-stp）10H₂O}_n（4）. were prepared in Ag（I）/2-sulfoterephthalicacid/4,4’-bipy-ridine system. Complex1has a2-D structure formed by2-Hstp （μ4-η1:η1:η1:η1） and bpy（μ2-η1:η1） bridges adjacent Ag（I） ions. The molecularstructure of2,3and4are cation-anion species, forming3-D polymersby hydrogen bond, respectively.In Chapter3, in Ag（I）/2-sulfoterephthalicacid/amino-pyridine system,ten Ag（I） complexes were obtanined by solvent volatilization andhydrothermal method, including:{[Ag₃（2-stp）（2-apy）₂（H₂O）]2H₂O}_n（5）,[Ag₃（2-stp）（2-apy）₂]_n（6）,[Ag₃（2-stp）（3-apy）（H₂O）]_n（7）,{[Ag₆（2-stp）₂（4-apy）₄]9H₂O}_n（8）,{[Ag₆（2-stp）₂（3-methyl-2-apy）₃] H₂O}_n（9）,[Ag₃（2-stp）（4-methyl-2-apy）₃]_n（10）,[Ag₃（2-stp）（4-methyl-2-apy）₂]_n（11）,{[Na₂Ag₁₈（2-stp）₄（2-Hstp）₄（5-methyl-2-apy）₁₆]28H₂O}_n（12）,[Ag₃（2-stp）（6-methy-2apy）₄] H₂O（13）,{[Ag₆（2-stp）₂（6-methyl-2-apy）8（H₂O）₂] H₂O}_n（14）. Among them, the complexes13is0-D structure, complexes14is1-D structure, complexes12is3-D structure, and the rest of thecomplexes are2-D structure. Show that amino replace and methyl replacethe position of the different in pyridine ring, to effect complexes’ spacestructure and the coordination model of2-sulfoterephthalic acid ligandscoordination model.In Chapter4, choosing Ag（I）/2-sulfoterephthalicacid/the rigid orflexible with N-donor as the auxiliary ligands to be starting object of this thesis through the solvent volatilization, we got eigth Ag（I） complexes,including:[Ag₃（2-stp）（pyz）_0.5]_n（15）,{[Ag₄（dpp）₄]2（2-Hstp）9H₂O}_n（16）,{[Ag（bpe）]₂[Ag₂（bpe）₂]₂2（2-stp）19H₂O}_n（17）,{[Ag₃（2-stp）（hmt）₂]3H₂O}_n（18）,{[Ag₃（2-stp）（2-apym）₃]2H₂O}_n（19）,{[Ag₂（2-Hstp）（4,6-dimethl-2-apym）₂（H₂O）] H₂O}_n（20）,{[Ag₂（2-stp）（H₂O）] Hdpa}_n（21）,[Ag₃（2-stp）（dpa）]_n（22）. In complexes17,2-sulfoterephthalic acid ligands is notcoordination, but as anionic balance charge. In the complexes of the rest,2-sulfoterephthalic acid ligands show different coordination model.Show that the rigid or flexible of auxiliary ligands will influence2-sulfoterephthalic acid ligands coordination model.
