The data obtained were combined with our previous density data to calculate the adiabatic compressibilities of each solution. Then, the infinite dilution values of partial molar adiabatic compressibilitiesK o s were evaluated. By subtraction of theK o s (K+) from those of the complexes, the values ofK o s for the halogeno complex ions [PtX4]2-, [PtX6]2-, [PdX4]2- and [PdX6]2- were determined. The values for the thiocyano complex ions [Pt(SCN)4]2- and [Pt(SCN)6]2- are positive, showing that the interaction of the ligand SCN- with the solvent water is very weak. Although the V 2 o behavior of the complex ions [PtCl6]2- and [PdCl6]2- differed only slightly, compressibility measurement has indicated that the ion [PdCl6]2- interacts more strongly than [PtCl6]2-.
