Abstract: Binuclear manganese complex [(phen)₂Mn₂(μ-O)(μ-Ac)₂ (H₂O)₂](ClO₄)₂·4H₂Owas synthesized by the reaction of MnAc 3·2H₂Owith phen in the HAc NaAc buffer(pH=4.0). X-ray diffraction result for the single crystal shows that the crystal belongs to monoclinic system, space group P2₁/n , with a =1.02528(5) nm, b =1.79275(9) nm, c =1.98414(10) nm, β =94.8430(10)°, V =3.6340(3) nm³, Z =4. There is a obsorption peak at 480 nm in UV-Vis spectrum. Cyclic voltammogram shows that the complex in MeOHundergoes a quasi-reversible one-electron redox reaction at E_1/2 =0.7 V.
