X-Ray structure and ionic conductivity studies of anhydrous and hydrated choline chloride and oxalic acid deep eutectic solvents

In this study, we report the structural, thermodynamic and electrochemical properties of deep eutectic solvents (DESs) formed from choline chloride and oxalic acid in anhydrous and di-hydrated form in a 1:1 molar ratio. As far as we are aware, this is the first joint X-ray diffraction-molecular dynamics study focussed on analyzing the structural features of DESs.
