    From extraction experiments and gamma-activity measurements, the extraction constant corresponding to the equilibrium H3O+(aq) + 1.Na+(nb) equil. 1.H3O+ (nb) + Na+ (aq) taking place in the two-phase water-nitrobenzene system (1: p-tert-butylcalix[4] arenetetrakis(N,N-dimethylacetamide)) was evaluated as -0.1 +/- 0.1. By using quantum mechanical DFT calculations, the most probable structure of the 1.H3O+ cationic complex species was derived.
