    • Because the complexation ability of Fe and Ga in aceto-nitrile/chloroform was too high to compare, the experiments were performed in acetonitrile/ tetrahydrofuran. Generally, the complexation ability decreases in polar solvent, so tetrahydrofuran was a good solvent for comparing the complexation ability
