| Abstract: | This research concerns the analysis of the binding properties of benzodiaza‐15‐crown‐5 ether derivatives towards different metal ions (Mg(II), Cd(II), Ni(II), Cu(II), Zn(II), Pb(II), Hg(II) and Ag(I)) in acetonitrile and water by potentiometric and optical methods. Benzodiaza‐15‐crown‐5 ether demonstrates high binding affinity towards Hg2+ (lg K11 = 12.7), whereas the stability constants of complexes with other studied cations varied from 3 to 6 logarithmic units.
