Switchable Phase Behavior of [HBet][Tf<sub>2</sub>N]–H<sub>2</sub>O upon Neodymium Loading: Implications for Lanthanide Separations
Task-specific ionic liquids (TSILs) present an opportunity to replace
traditional organic solvents for metal dissolution or separation.
To date, a thorough investigation
of the physical properties of biphasic TSIL–H<sub>2</sub>O
systems and the effects of metal loading is lacking. In this work,
the change in the liquid–liquid equilibrium of [HBet]Â[Tf<sub>2</sub>N]–H<sub>2</sub>O upon the addition of NdÂ(III)
is investigated by cloud-point measurements. The addition of Nd(III), drops the upper critical solution temperature by over 20 °C. Further investigation
of the [HBet]Â[Tf<sub>2</sub>N]–Nd(III) system
led to the formation of single
crystals of [Nd<sub>2</sub>(H<sub>2</sub>O)<sub>8</sub>(ÎĽ<sub>2</sub>-Bet)<sub>2</sub>(ÎĽ<sub>3</sub>-Bet)<sub>2</sub>]Â[(Cl)<sub>2</sub>(Tf<sub>2</sub>N)<sub>4</sub>] from the TSIL phase
