Tetrachloroferrate containing ionic liquids: Magnetic- and aggregation behavior

The magnetic behavior of a binary salt of tricaprylylmethylammonium tetrachloroferrate and tricaprylylmethylammonium chloride, [A336][FeCl 4]0.73[Cl]0.27, was evaluated. With a magnetic susceptibility of 0.011 emu mol- 1 this binary salt exhibited a remarkable response to an external magnetic field. Dynamic light scattering (DLS) measurements allowed to study the aggregation behavior of [A336][FeCl 4]0.73[Cl]0.27 as well as of further magnetic ionic liquids [PR6,6,6,14][FeCl4] and (BMIM)[FeCl 4] in ethylacetate and ethanol. © 2010 Elsevier B.V.
