摘要：

Five manganese complexes of Schiff base were synthesized: [ Mn (IV.IV) (mu-O) (Salen) ] (2) . DMF . H2O (1), [Mn-IV.IV (mu-O) (5-BrSalen)](2) . DMF . 0.5H(2)O (2), {Mn-IV.IV(mu-O) [ Sal(1, 2-pn)]}(2) . H2O (3), {Mn-IV.IV (mu-O) [5-Br-Sal (1, 2-pn)]}(2) . H2O (4), {Mn-IV.IV(mu-O) [ 5-CH3-Sal (1, 2-pn)]}(2) . 2H(2)O (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 Mn-2(IV) pair at room and low temperature, and the interactions of complex 3 are weaker than complex 1.
