Containing Sulfide / Over-the Sulfur Bond Dicarboxylic Acid Metal Complexes Synthesis And Structural Chemistry Research

In this thesis, six transition metal coordination complexes based on the sulfide ordisulfide containing alkyldicarboxylic acids have been synthesized through theself-assemble reaction. Meanwhile, five supramolecular complexes constructed from theaforementioned acids and bis(pyridyl) amines have also been obtaind by the co-crystalstrategy. All the complexes are characterized by element analysis, IR, PL, XRD andsingle crystal X-ray diffraction. The carboxyl groups in the silver(I) based complexesexhibit diverse coordination modes and form high dimensional complexes with theassistance of monodentate S atom. It should be noted that the introduce of the4,4'-bpyis beneficial to the formation of the porous framework. Some weakly interactions, suchas, O-H···O, N-H···O, Ï€-Ï€ stacking, N-H···π, are detected in the supramolecularcomplexes. Moreover,4-sulfinobenzoic acid is synthesized for the first time andemployed to react with Zn(II) and Cd(II) cations, thus leading to the formation of fourZn(II)/Cd(II)4-sulfinobenzoate complexes. Interestingly, another two Zn(II)/Cd(II)4-sulfobenzoate complexes and one Zn(II) complexes are also been obtained underhydrothermal conditions by in situ reaction. The sulfinate ligand present different μ2-η²,μ2-η²(carboxyl group):η₁(sulfinate group), and monodentate mode. The structureanalyses of these complexes indicate that the coordination ability obeys the followingsequence: sulfinate group> carboxyl group> sulfonate group.
