%X The hydrogen sorption of mixtures of magnesium amide (Mg(NH2)2) and lithium hydride (LiH) with different molecular ratios have been investigated using in-situ neutron diffraction; the experiments were performed at D20/ILL and SPODI/FRMII. The results reveal a common reaction pathway for 1:2, 3:8 and 1:4 magnesium amide: lithium hydride mixtures. Intermediate reaction steps are observed in both ab- and desorption. The thermodynamic properties of the system at 200 °C are not changed by the addition of excess lithium hydride. This finding has important implications for the tailoring the characteristics of this promising hydrogen storage material.
