Description	From extraction experiments and γ-activity measurements, the exchange extraction constant corresponding to the equilibrium N2H+5 (aq) + 1.Cs+(nb) <–> 1.N2H+5 (nb) + Cs+(aq) taking place in the two–phase water–nitrobenzene system (1 =hexaarylbenzene–based receptor; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex (N2H+5, 1.Cs+)= –1.2. Further, the stability constant of the complex 1.N2H+5 in nitrobenzene saturated with water was calculated: log βnb (1.N2H+5) = 5.6. Using quantum chemical calculations, the most probable structure of this complex was solved. In this complex, the cation N2H+5 synergistically interacts with the polar ethereal oxygen fence and with the central hydrophobic benzene bottom via cation–π interaction. Finally, the calculated binding energy of the resulting complex is –270.5 kJ/mol, confirming the relatively high stability of the considered cationic complex species.
