Weak complexes of sulphur and selenium. Part III. Effect of solvent on the stability of 1 : 1 complexes of sulphur dioxide, sulphinyl dichloride, and sulphonyl dichloride with halogen ions
Abstract
The complex species SO2′X–, SOCl2′X–, and SO2Cl2′X–(X = Cl, Br, and I) have been studied in acetonitrile, dimethyl sulphoxide (dmso), and water (for SO2′X– species only). It appears that solvation of halide ions by dmso is important in deciding the stabilities of the different species.
