Abstract
The study of complex-formation between iodine and crown ethers (CE) in two-phase systems (water containing I2 + KI and dichloroethane contai ning CE 12-C-4, 15-C-5, 18-C-6, B-15-C-5, DB-18-C-6, 4'-NO2-B-15-C-5) has led to the following conclusions: (i) charge-transfer complexes wh ich contain the l3(-) anion species are formed in the organic phase; ( ii) the combination ratios and equilibrium constants of these complexe s depend on the type of CE present in the organic phase.
