Solubility and solvation of pyronato and pyridinato complexes of aluminum, gallium, and indium in alcohol–water mixtures

Solubilities are reported for aluminum, gallium, and indium tris-ligand complexes of the pyrones maltol and ethylmaltol and of a number of 4-pyridinones in water–methanol and water–tert-butyl alcohol solvent mixtures, at 298.2 K. Trends and patterns in transfer chemical potentials derived from these solubilities are discussed in terms of the dependence of solvation on the nature of the ligand, the metal, and the cosolvent.
