: The binding properties of amido derivatives of p-tert-butyl calix[4]arene (1-3) towards various anions (spherical halides, planar trigonal nitrate and tetrahedral hydrogen sulphate) as their tetrabutyl ammonium (TBA) salts were studied by 1H NMR technique and using EquiChem program. The stability constants, logβij, varying from 0.94 to 2.05 were determined for the mononuclear complexes.
