Popis: The acid-base and coordination properties of N-(thio)phosphorylated thioureas and thioamides R1C(X)NHP(Y)R 2 2 , where X, Y = S, O (in various combinations); R1 = t−Bu, i-Pr, PhNH, Ph; R2 = (OPr−i), with respect to Co(II), Ni(II), Zn(II), and Cd(II) ions have been studied by pH-metry and UV spectrometry in an organic solvent. The pK values, the stability constants logβ and the maximum accumulated fractions of complex species in the solution have been calculated.
