N,N-Bis(2-Hydroxyethyl)taurine: Synthesis, Structure, and Stability of the Complexes with Cobalt(II) and Nickel(II)

Resumo

The complex formation of N,N-bis(2-hydroxyethyl)taurine with cobalt(II) and nickel(II) ions is studied. The acidic ionization constant of the ligand is determined by the potentiometric method. The stability constants of the complexes with the metal ions are calculated. Bis(N,N-di(2-hydroxyethyl)taurinato)cobalt(II) (II) and bis(N,N-di(2-hydroxyethyl)taurinato)nickel(II) monohydrate DMF disolvate (I) are synthesized, and their structures are studied by X-ray diffraction analysis (CIF file CCDC no. 1822829 (II)).
