摘要：

A series of dinuclear complexes of ruthenium(II) have been synthesized in which alpha-azodiimines {such as azobis-(2-pyridine), apy, and azobis(4-methyl-2-pyridine), mapy} act as the bridge and 2,2'-bipyridine (bpy) or 4,4'-dimethyl-2,2'-bipyridine (Me(2)bpy) as the terminal ligands. The diastereoisomeric forms of each species {Delta Lambda (meso) and Delta Delta/Lambda Lambda (rac)} have been separated by cation-exchange chromatography and characterized by H-1-NMR spectroscopy. Electronic spectral and electrochemical studies show then to be differences in inter-metal communication between the diastereoisomeric forms in each case. Comparison of the spectroelectrochemical behavior of the range of complexes has allowed unequivocal assignment of the site of the successive reduction processes observed in dinuclear complexes of this type.
