The extraction constant of the silver ion–dibenzo-18-crown-6 (DB18C6) complex between benzene and water and the complex-formation constant of DB18C6 with silver picrate in benzene were determined at 25 °C. The Ag<SUP>+</SUP>–DB18C6 complex is much more extractable than the Ag<SUP>+</SUP>–18-crown-6 one. The Ag<SUP>+</SUP>–DB18C6 complex is much more stable for benzene than for aqueous solutions.
