This study aims to investigate the low temperature phase behaviour of Li(ND3)4Cl, Li(ND3)4Br and Li(ND3)4I. To the authors knowledge the only structural data that exists on these compounds are two RT XRD studies on Li(NH3)4Br and Li(NH3)4I which do not include hydrogen positions[4]. A variable temperature ND study would be able to determine the following:1)Accurate D positions for phases at RT and 5K which are essential for accurate simulations of the molecular dynamics and lattice dynamic simulations.2)Whether any phase changes occur as the halide ammines are cooled.3)An overview of the effect of changing anion on the relative onset of any phase changes.
