N2 - The paper presents data on the synthesis and study of the acid–base and complexing properties of N-hydroxyalkyl taurine derivatives. The ammonium group dissociation constants of the reagents were determined. The complex formation of taurine derivatives with transition and alkaline-earth metal ions was studied. Trends in the influence of the structure of ligands on the stability constants of their transition and alkaline-earth metal complexes were elucidated. In most cases, the studied ligands form most stable complexes with copper(II) ions. The decrease in amino group basicity in response to the incorporation of additional hydroxyl and/or sulfoethyl groups into a derivative leads to the differentiation of the ligand properties toward the studied ions. The data of this work can help expand the application range of the studied ligands, which can potentially be used as components of buffer solutions where there is the need to avoid or minimize complex formation in solution.
