摘要：

The aim of this study was to determine rate constants for the release of NO from an iron(II) nitrosyl complex dissolved in a typical imidazolium-based ionic liquid, [emim][dca], using an NO trapping technique combined with stopped-flow measurements. The anionic component of the selected ionic liquid, viz. [dca] (dicyanamide), was found to coordinate to the Ru-III(edta) complex used as trapping agent, and hindered its successful application. Further investigations in aqueous solution revealed thermodynamic and kinetic data for the formation of the [Ru-III(edta)(dca)](2-) complex and its reaction with NO to form the corresponding nitrosyl complex. The results obtained under conditions similar to those in the ionic liquid indicated a much slower formation of the nitrosyl complex in [emim][dca] compared to that reported for the formation of this complex in aqueous medium.
