Description	From extraction experiments and gama-activity measurements, the extraction constant corresponding to the equilibrium Cs+ (aq) + A? (aq) + 1(nb) ? 1?Cs+(nb) + A?(nb) taking place in the two-phase water-nitrobenzene system (A? = picrate, 1 = dibenzo-30-crown-10; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex (1?Cs+,A?) = 4.0 +- 0.1. Further, the stability constant of the 1?Cs+ complex in nitrobenzene saturated with water was calculated for a temperature of 25 °C: log betanb (1?Cs+) = 5.9 +- 0.1. Finally, by using quantum-mechanical DFT calculations, the most probable structure of the resulting cationic complex species 1?Cs+ was derived.
