Liquids intermediate between "molecular" and "ionic" liquids: liquid ion pairs?

Chem Commun (Camb). 2007 Oct 7:(37):3817-9. doi: 10.1039/b710014k.

Abstract

Ionic liquids comprised of tetradecyltrihexyl- and tetrabutyl-phosphonium cations paired with chloride or sulfonyl amide anions exhibit properties that reflect strong ion association, including comparatively low viscosity as well as a degree of volatility, and hence exemplify an interesting intermediate state between true ionic and true molecular liquids.
