Outline of Final Research Achievements

Chloro complex formation constants and the heats of complexation of copper (II) in ionic liquids lie within them in conventional molecular solvents such as DMF and acetonitrile. In addition, the entropy term was found to be the driving force of the complexation. They indicate that the complexation mechanism in ionic liquids is similar to that in the conventional liquids, despite their uniqueness as a solvent. On the contrary, minor solvent dependence of the complexation constants and athermal ligand exchange of the solvate are interestingly observed in ionic liquids. This will be attributed to the fact that the solvent species in ionic liquids have a negative charge that causes a significant inter-ligand interaction in the primary solvation shell.
