A conductance study of the interaction of NH4 + and Tl+ ion with 18-crown-6 (18C6), ditertbutyl-dicyclohexyl-18-crown-6 ((t-but)2DC18C6), diaza-15-crown-5 (DA15C5), dibenzo-21-crown-7 (DB21C7) and dibenzo-24-crown-8 (DB24C8) in acetonitrilemethanol mixture was carried out at 25.0š0.1°C. The formation constants of the resulting 1:1 complexes were determined from the molar conductance-mole ratio data and found to vary in the order of DA15C5 > 18C6 > DB21C7 > (t-but)2DC18C6 > DB24C8, in the case of Tl+ ion in 100% MeOH, and in the order of: DA15C5 > 18C6 > (t-but)2DC18C6 > DB21C7 > DB24C8 for the NH4 + ion in 100% AN and AN-MeOH mix tures. The sta bil i - ties of the complexes for NH4 + and Tl+ ions varied in versely with the Gutmann donicity of the solvent with the ex cep tion of DA15C5-Tl+ complexes. The in fluence of substituents on the polyether ring and cavity size is discussed.
