Magnetic ionic liquids (MILs) are molten salts formed entirely of ions, which have a melting point below 100 ºC. The great variety of possible combinations of anions and cations makes them a huge potential field of development of smart materials with a primary focus in Materials Science; supported by the growing interest of chemists, physicists, and materials scientists. In the search of developing new MILs with enhanced magnetic response at room temperature, we have synthetized a new family based on imidazolium cation and [Fe2OX6]- anion. Therefore, in this proposal we ask for 2 days at D2B high resolution diffraction instrument to obtain accurate magnetic structure characterization and phase transition of two new MILs with formula Dimin[Fe2OX6]- (X = Cl and Br). The magnetic structure characterization of these AF compounds with polar space group will be carried out using D1B high flux and medium resolution diffractometer, for that we ask for two days of beam-time.
