摘　　要：Binuclear mixed valent manganese complex [(Phen) 2Mn( μ O) 2Mn(Phen) 2] (ClO 4) 3·CH 2ClCOOH·2H 2O was synthesized by the reaction of [Mn 3O(O 2CCH 2Cl) 6(C 5H 5N) 2(H 2O)] ·CH 2ClCOO·H 2O with Phen and NaClO 4 in the CH 2ClCOOH CH 2ClCOONa buffer (pH=4.0). X ray diffraction result for the single crystal shows that the crystal is triclinic, space group P 1, with a =\{1.182 64(7)\} nm, b =1.449 32(8) nm, c =1.664 99(9) nm, α =104.585 0(10)°, β =97.123 0(10)°, \{ γ =\}106.921 0(10)°, V =2.581 6(3) nm 3, Z =2, D c=1.660 g·cm -3 , R =0.052 2. A peak at 640 nm in UV Vis spectrum is designed to the electronic transition of bridge legend O 2- to Mn(Ⅲ). Cyclic voltammogram shows that the complex in CH 3CN undergoes two quasi reversible one electron redox reactions at E 1/2 =1.25 V and E 1/2 =0.33 V, respectively.Binuclear mixed valent manganese complex [(Phen) 2Mn( μ O) 2Mn(Phen) 2] (ClO 4) 3·CH 2ClCOOH·2H 2O was synthesized by the reaction of [Mn 3O(O 2CCH 2Cl) 6(C 5H 5N) 2(H 2O)] ·CH 2ClCOO·H 2O with Phen and NaClO 4 in the CH 2ClCOOH CH 2ClCOONa buffer (pH=4.0).
