Abstract The reaction of [RuIII(EDTA)(H2O/OH)]−/2− (EDTA4− = ethylenediaminetetraacetate) with bisulfide (HS−) and persulfide (HSS−) leading to the formation of a dinuclear disulfur-bridged [(EDTA)RuIIISSRuIII(EDTA)]4− product has been studied spectrophotometrically. Kinetics of the reaction of [RuIII(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)RuIIISSRuIII(EDTA)]4−, in the reaction of [RuIII(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.

[RuIII(EDTA)(H2O/OH)]-/2- 与二硫化物和过硫化物在水溶液中的反应：动力学和机械研究

摘要 [RuIII(EDTA)(H2O/OH)]−/2− (EDTA4− = 乙二胺四乙酸酯) 与二硫化物 (HS−) 和过硫化物 (HSS−) 的反应导致形成双核二硫桥联 [(EDTA) )RuIIISSRuIII(EDTA)]4− 产物已通过分光光度法进行了研究。[RuIII(EDTA)(H2O/OH)]-/2- 与 HS- 在水溶液中作为 [HS-] 的函数在恒定 pH 值 8.2（磷酸盐缓冲液）和温度（20 ℃）。在 [RuIII(EDTA)(H2O/OH)]-/2- 与 HSS- 的反应中，产物复合物 [(EDTA)RuIIISSRuIII(EDTA)]4- 的形成通过 ESI-MS 研究确定。提出了与光谱和动力学数据一致的工作机制。
