Preliminary Complexation Studies of Bis-(8-Hydroxyquinoline)-substituted Tetraaza-15-crown-5 with Various Metal Ions
Abstract
Complexation of bis(8-hydroxyquinoline)-substituted tetraaza-15-crown-5 with Cu(2+), Co(2+), Ni(2+), Zn(2+), Cd(2+), and Pb(2+) was evaluated potentiometrically in aqueous solution (0.10 M Me4NCl) at 25 deg C. Ligand 1 formed very stable complexes with these metal ions. The UV-Vis spectra of ligand 1 and its complexes were examined in an aqueous acetic acid buffer solution (pH 4.7). The 1-Cu(2+) complex provided a new absorption band at 258 nm.
