合成了3种双核钌配合物[Ru(bpy)2]2{[(PyCHN)-Ph-O-C6H4-]2R}(ClO4)4,bpy=2,2′-联吡啶,PyCHN=N-2-吡啶亚甲基,R＝无(1),-C(CH3)2(2),-SO2(3)并进行了有关表征.电化学研究表明:配合物3的△E和K值最大,说明苯环和硫原子之间存在着较强的(p(π)-dπ相互作用,有助于获得较强的金属-金属相互作用.配合物1,2,3都有混合价,通过Hush方程可以得到Vab的值大概为320～420 cm-1.这些结果表明:Schiff碱作为桥配体对于调配金属-金属相互作用并将其作为分子导线起着特殊的作用.

Binuclear ruthenium complexes [Ru (bpy)2]2 {[(PyCHN)-Ph-O-C6H4-]2R} (ClO4)4 where bpy =2,2′-bipyridine,PyCHN=N-2-pyridylmethylene,R=none for 1,-C(CH3)2 for 2 and-SO2 for 3,have been prepared and characterized.Electrochemical studies reveal that the ΔE and Kc for complexes 1,2 and 3 are surprisingly and unprecedentedly large.However,the complex 3 gives larger ΔE and Kc.It is suggested that the strong (p(π)-d)π interactions between the phenyl rings and the sulfur atom should be helpful to achieve stronger metal-metal interaction.For mixed-valence species of complexes 1,2 and 3,Vab can be obtained by Hush equation with a value of 320～420 cm-1.These results indicate that the Schiff base bridging ligands show particular efficiency for mediating the metal-metal interactions and for using as molecular wires.
