Binuclear manganese complex [(bipy)2Mn2(μ-O)(μ-Ac)2(H2O)2](CIO4)2 was synthesized by the reaction of MnAc3 · 2H2O with 2,2’-bipyridine in the HAc-NaAc buffer (pH = 4.0). X-ray diffraction result for the single crystal shows that the crystal is monoclinic, space group C2/C, with a = 3.4082(7), 6 = 0.8644(2), c= 2.174 9(4) nm,β= 105.2°, V =6.186(2) nm3, Z= 8. There are two very strong peaks of UV-Vis spectrum in the range of 400-600 nm, which are similar to those of Mn catalase and Mn ribonuleotide reductase extracted from organisms. Cyclic voltammogram shows that the complex in CH3CN undergoes quasi-reversible one-electron reduction and oxidation at E1/2=1.15V.
