New ligand systems were synthesized by condensation of o-tosylaminobenzaldehyde with quinolin-2-ylhydrazine and 1-methyl-1H-benzimidazol-2-ylhydrazine. Acid-base properties of the resulting hetarylhydrazones and their complexing power toward bivalent copper, nickel, and cobalt ions were studied. The stability constants of the complexes were determined.
