乙酰水杨酸制备双核水杨酸锰(IV)配合物

The binuclear manganese (Ⅳ) [Mn2(Hsal) 4(OH) 4] (Hsal=o-OHC6H4COO) complex was synthesized by acetylsalicylic acid ligand with manganese which is trace elements necessary for the human. The synthesis of complex was carried out by reaction of NaHCO3 with acetylsalicylic acid (equimolar amounts) in water, and mixed with MnSO4 (the mole rate of MnSO4: acetylsalicylic acid=1:2) under stirring at 70℃ for 30min, with tert-butyl alcohol as precipitant, collected insoluble material from the solution by filtration, then crystallization growth obtained by solvent diffusion method in ethanol benzene. The mixed solvents was analyzed to be better. Unfortunately we did not get manganese acetylsalicylate, the reason was directed. Single crystal diffraction, FT-IR, mass spectrum of complex was used. TG, UV-Vis, fluorescence spectrum and magnetic properties were inspected. Biological pharmaceutical functions, fluorescence and magnetic property of complex can be widely developed and utilized.
