Crystal structure determination of the (trimim)[FeBr4] hybrid halometallate compound
In recent studies, we have found that imidazolium magnetic ionic liquid based on tetrahaloferrate anions display very interesting magnetic and dynamic phenomena. Now, we synthesized the compound trimim(FeBr4) (trimim: 1,2,3-trimethylimidazolium), which shoes three-dimensional magnetic order at low temperatures. In order to solve the magnetic structure, it is necessary to know the nuclear structure. The structure obtained by previous single-crystal X-Ray and powder synchrotron X-Ray diffraction does not fit the powder neutron diffraction data acquired in the D1B instrument, possibly due to the reorientation of the imidazolium rings below 160 K. In order to solve the structure at low temperatures, we will grow crystals suitable for single-crystal neutron diffraction. With this objective, we kindly apply to 8 days on D19 to carry out high resolution single-crystal neutron diffraction or, alternatively, 12 days in D9.
