Outline of Final Research Achievements

The goals of this work are 1) to clarify the extremely desolvated state of metal ions in ionic liquids, and 2) to find a novel and well-regulated complexation not depending on steric effect. As one of the main findings in the first aim, the utmost deslovated state of Co(II) ion was clarified to be [Co(OH2)4]2+. In the second aim, the coordination interaction between the extremely "hard" acid (e.g. uranyl ion) and "soft" base (e.g. sulfur donor ligand like tetramethylthiourea) was actually demonstrated for the first time.
