The homochiral multinuclear Ru complexes of the oligomeric bibenzimidazoles were synthesized using Lambda-[Ru(bpy)(2)(PY)(2)][(-)-O,O-dibenzoyl-L-tartrate]-12H(2)O as an enantiornerically pure building block. The complexations proceed with the retention of configuration to provide well-defined mononuclear, dinuclear, tetranuclear, and octanuclear Ru complexes successfully. The optical purity and the absolute configurations of the complexes were determined by NMR and circular dichroism spectrometry. The rare X-ray structure of a tetranuclear complex Lambda(4)[(Ru(bpy)(2))(4)(bis(BiBzlm))](PF6)(4) was resolved, The crystallographic analysis reveals that all the four Ru centers have A octahedral configurations, with a Ru-Ru separation of 5.509 angstrom across the bridging bibenzimidazole ligand, which maintains near coplanarity. The UV-vis spectroscopic and electrochemical properties of the homochiral multinuclear assemblies were studied, indicating weak electronic communications between the metal centers.
