摘要： MnAc3·2H2O在pH=4.0的HAc-NaAc缓冲溶液中和邻菲罗啉(phen)反应,制得了双核锰()配合物[(phen)2Mn2(μ-O)(μ-Ac)2(H2O)2](ClO4)2·H2O,并进行了红外光谱表征.X射线单晶衍射表明,该晶体属单斜晶系,空间群P21/n,晶胞参数: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,Dc=1.669g·cm-3.紫外可见光谱在480nm处有一个吸收峰.循环伏安实验说明,此配合物在乙腈溶液中经历了一个半可逆的一电子氧化还原过程.

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 E1/2 =0.7 V.
