摘要 由Ru2(μ-O2CCH3)4Cl为前体配合物,合成了两种氧原子作为电子供体的双核四乙酸钌(Ⅱ,Ⅲ)配合物[Ru2(μ-O2CCH3)4(L)2]PF6(L=H2O,MeOH,分别用(1)、(2)表示)。采用元素分析、红外光谱、紫外-可见吸收光谱对配合物进行了表征。考察了该配合物的电化学性质,通过循环伏安法,测得[Ru2(μ-O2CCH3)4(L)2]+/0电对的氧化还原半波长电位为535 mV,与其他中等强度的路易斯碱配合物相当。 The reaction of Ru2 (μ--O2CCH3)4Cl with Lewis base ligand leading to the formation of O-- donor ruthenium complex of [Ru2 (μ--O2CCH3)4 (L)2] PF6 (L= H2O, MeOH) has been synthesized and characterized by elemental analysis, IR and UV--vis absorption spectroscopies. The electrochemical properties of ruthenium ( Ⅱ, Ⅲ) complex have been studied by means of cyclic voltametry. The redox potential for the [Ru2 (μ--O2CCH3) 4 (L)2]+/0 couple is 535 mV (vs. Ag/AgCl) which is comparable to other moderately strong Lewis base adducts.
