The interaction of diglycollic acid ligand with iron(III), cobalt(II), nickel(II) and copper(II) salts was investigated potentiometrically and spectrophotometrically. Only 1:1 complexes were formed in solution and solid. The p K's of the ligand and its complexes were computed. The electronic absorption spectra of the complexes depict the octahedral geometry. The infra‐red spectra of the ligand and its complexes were discussed.
