SYNTHESIS, CHARACTERIZATION AND PHYSICOCHEMICAL STUDIES OF WEAKLY INTERACTING REDOX-RESPONSIVE BINUCLEAR COMPLEXES INCORPORATING ETHYLENEDIAMINETETRAACETATORUTHANATE(III)

摘要

Novel binuclear complexes of the type [{Ru(edtaH)}(2)L] [edta = ethylenediaminetetraacetate, L = pyrazine, 4,4'-bipyridyl, 3,3'-dimethyl-4,4'-bipyridyl, trans-1,2-bis(4-pyridyl)ethylene] have been synthesized and characterized by physicochemical methods. All the complexes showed weak metal-metal interaction, depending on the nature of the bridging ligand, L. The electrochemical and magnetic susceptibility measurements are consistent with weak interactions between the ruthenium centres. [References: 34]
