Abstract
The stabilizing effect of alkyl pyridinium cations (RPy+) on the equilibriu m of formation of the tetrahedral complex [Co(SCN)(4)](2-) in aqueous solut ions of nonionic surfactants [T = Tween 20 (40), Triton X-100] disclosed fo r the first time, was explained by the formation of species with the compos ition (RPy)(2)[Co(SCN)(4)] localized in nonionic micelles.
