Physico-Chemical Properties of Magnetic Dicationic Ionic Liquids with Tetrahaloferrate Anions.

ABSTRACT: A series of imidazolium-based symmetrical and asymmetrical dicationic ionic liquids (DcILs) with alkyl spacers of different length and with [FeCl₃ Br]^- as counter ion have been synthesized. The synthesized DcILs are characterized by using FTIR and Raman spectroscopy as well as mass spectrometry, along with single-crystal XRD analysis. Physicochemical properties such as solubility, thermal stability and magnetic susceptibility are also measured. These compounds show low melting points, good solubility in water and organic solvents, thermal stability, and paramagnetism. The products of molar susceptibility and temperature (χ_mol ⋅T) for the synthesized DcILs have been found between 4.05 to 4.79 emu mol^-1  K Oe^-1 and effective magnetic mom
