QENS studies of the ammines of magnesium chloride

Abstract: The ammoniates of simple salts, such as MgX2 (X=Cl, Br, I), known as ammines, have attracted much interest recently as they offer potential as both hydrogen and ammonia storage materials, amongst other applications. The magnesium halide ammines can accommodate up to 6 equivalents of ammonia (ca. 50 wt%) as [Mg(NH3)n]Cl2 (0 ≤ n ≤ 6) However, there is, as yet, no understanding of the mechanism of ammonia binding and transport through the solid and only qualitative understanding of how and why ammonia binds to the metal centers. Quasi-elastic neutron scattering (QENS) is frequently used to study diffusion of species in solids and allows experimental diffusion coefficients to be extracted via modelling the transport mechanisms. Here we wish to use the OSIRIS QENS to investigate the mobility of ammonia in MgCl2 ammines.
