of the complexes has been established by elemental analysis, spectral methods (FT-IR, electronic, (1)H NMR, UV/Vis and electrochemical (cyclic voltammetry) techniques. The crystal structure of complex 1 is reported. The Ru(II) oxidation state is greatly stabilized by the novel tridentate ligands, showing Ru(III/II) couples ranging from 0.93-1.27 V vs. Cp2Fe/Cp2Fe(+). The absorption spectrum of 1 in dichloromethane
具有通式[Ru(II)(LY)(bpy)Cl](PF6)LY = YC6H4N = NC(COCH3)= NC9H6N,Y = H(1),合成了CH3(2),Br(3),NO2(4)和bpy = 2,2'-bipyrdine}。基于偶氮亚胺-喹啉的配体表现为NN'N''三齿供体,并通过偶氮-N',亚胺-N'和喹诺酮-N''氮原子与钌配位。通过元素分析,光谱方法(FT-IR,电子,(1)H NMR,UV / Vis和电化学(循环伏安)技术)确定了配合物的组成,报道了配合物1的晶体结构。 II)新型三齿配体极大地稳定了氧化态,显示Ru(III / II)对相对于Cp2Fe / Cp2Fe(+)的范围为0.93-1.27V。
