Abstract: Five manganese complexes of Schiff base were synthesized: [MnⅣ,Ⅳ(μ-O)(Salen)]2·DMF·H2O (1), [MnⅣ,Ⅳ(μ-O)(5-BrSalen)]2·DMF·0.5H2O (2), {MnⅣ,Ⅳ(μ-O)[Sal(1,2-pn)]}2·H2O (3), {MnⅣ,Ⅳ(μ-O)[5-Br-Sal(1,2-pn)]}2·H2O (4), {MnⅣ,Ⅳ(μ-O)[5-CH3-Sal(1,2-pn)]}2·2H2O (5), and were characterized by element analysis, IR and UV-Vis spectra. The results of cyclic voltammogram show that Schiff base ligands can drop the potential of manganese and steady high oxide state of manganese. The magnetic properties of 1 and 3 have also been studied. The results show that there is a weak ferromagnetically coupling of MnⅣ2 pair at room and low temperature, and the interactions of complex 3 are weaker than complex 1. |
