Abstract

The reaction of [Ru-III(EDTA)(H2O/OH)](?)(/2)(?) (EDTA(4?) = ethylenediaminetetraacetate) with bisulfide (HS?) and persulfide (HSS?) leading to the formation of a dinuclear disulfur-bridged [(EDTA)(RuSSRuIII)-S-III(EDTA)](4?) product has been studied spectrophotometrically. Kinetics of the reaction of [Ru-III(EDTA)(H2O/OH)](?)(/2)(?) with HS? was studied in aqueous solution as a function of [HS-] at a constant pH of 8.2 (phosphate buffer) and temperature (20??C). Formation of the product complex, [(EDTA)(RuSSRuIII)-S-III(EDTA)](4?), in the reaction of [Ru-III(EDTA)(H2O/OH)](?)(/2)(?) with HSS? was identified by ESI-MS studies. A working mechanism in agreement with the spectroscopic and kinetic data is presented.
