摘　　要：合成并表征了3个Schiff碱配体及由其桥联的3个双核钌配合物,并通过核磁共振谱、红外光谱、质谱及元素分析等测试手段对配体及化合物进行了表征.电化学测试结果表明,在3个双核配合物中存在着分子内的金属-金属间相互作用,且连接两个金属的桥配体是影响金属间相互作用强弱的关键因素.Three binuclear ruthenium complexes with two Ru（bpy）2 units, where bpy = 2,2＇-bipyridine linked by Schiff base were synthesized and characterized by Elemental analyses （C, H and N）, IR spectra, Electrospray mass spectra and 1H NMR. Electrochemical studies revealed that the three complexes exhibited weak metal-metal interactions. And the comproportionation constant Kc changed with the different bridge ligand, which indicated that the bridge ligand played a significant role in influencing △E and Kc for the dinuclear ruthenium complexes.
