X-ray scattering data from four pairs of ionic liquids (ILs) are compared. The alkyl-substituted cations show a first sharp diffraction peak between 3 and 4 nm(-1) that is not observed for ILs having cations with ether- or hydroxy-substitutions. These observations indicate a significant difference in the intermediate range order for these liquids.
Specific cation-anion interactions for two pairs of isoelectronic ionic liquids (ILs) have been investigated using nuclear Overhauser effect (NOE) 2D NMR methods to explore proximities between ions. The four ILs comprise the bis(trifluoromethylsulfonyl)amide anion paired with the following cations: triethyloctylammonium,(More)
Four paramagnetic ionic compounds have been prepared and their magnetic, structural and thermal properties have been investigated. The four compounds are methylbutylpyrrolidinium tetrachloroferrate(III) ([Pyrr(14)](+)/[FeCl(4)](-)), methyltributylammonium tetrachloroferrate(III) ([N(1444)](+)/[FeCl(4)](-)), butylmethylimidazolium tetrachloroferrate(III)(More)
