Abstract: Binuclear mixed-valent manganese complex [(Phen)2Mn(μ-O)2Mn(Phen)2] (ClO4)3·CH2ClCOOH·2H2Owas synthesized by the reaction of [Mn3O(O2CCH2Cl)6(C5H5N)2(H2O)] ·CH2ClCOO·H2O with Phen and NaClO4 in the CH2ClCOOH-CH2ClCOONa buffer (pH=4.0). X-ray diffraction result for the single crystal shows that the crystal is triclinic, space group P, with a =1.18264(7) nm, b =1.44932(8) nm, c =1.66499(9) nm, α =104.5850(10)°, β =97.1230(10)°, γ =106.9210(10)°, V =2.5816(3) nm3, Z =2, Dc=1.660 g·cm-3, R =0.0522. Apeak at 640 nm in UV-Vis spectrum is designed to the electronic transition of bridge legend O2- to Mn(Ⅲ). Cyclic voltammogram shows that the complex in CH3CN undergoes two quasi reversible one electron redox reactions at E1/2 =1.25 Vand E1/2=0.33 V, respectively.
