Two novel paramagnetic ionic liquids, comprised of a 1-ethyl-2,3-dimethylimidazolium (Edimim) cation and a tetrahaloferrate(III) (FeX4) (X = Cl and Br) anion were synthesized and characterized by thermal, structural, Raman spectroscopy and magnetic studies. The crystal structures, determined by synchrotron X-ray powder diffraction and single crystal X-ray diffraction at 100 K for Edimim[FeCl4] and Edimim[FeBr4] resp., are characterized by layers of cations (in non-planar configuration) and anions stacked upon one another in a three-dimensional (3D) manner with several non-covalent interactions: halide-halide, hydrogen bond and anion-蟺. Magnetization measurements show the presence of three-dimensional antiferromagnetic ordering below the N茅el temperature (TN) with the existence of a noticeable magneto-crystalline anisotropy in the bromide compound The corresponding magneto-structural correlations evidence that the 3D magnetic ordering mainly takes place via Fe-X路路路X-Fe (X = Cl and Br) interactions, displaying a higher superexchange magnetic interaction between the planes. Comparison with the Emim[FeX4] (X = Cl and Br) phases (Emim: 1-ethyl-3-methylimidazolium) reveals that the methylation at the C(2) position onto the imidazolium cation ring causes an increase of the m.p. and a decrease of the TN. In contrast, the comparative study with Dimim[FeX4] (X = Cl and Br) compounds (Dimim: 1,3-dimethylimidazolium) shows a lower TN in the chloride compound, Edimim[FeCl4], whereas it is higher for the bromide, Edimim[FeBr4]. This fact is attributed to the spin delocalization of iron atoms in [FeBr4]– and discards the hypothesis that a bigger imidazolium ion size causes a weaker magnetic coupling in paramagnetic ionic liquids based on tetrahaloferrate anions and imidazolium cations with 3D magnetic ordering in its solid state. In the experiment, the researchers used many compounds, for example, 1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6Product Details of 92507-97-6).
