We request 2 days on GEM to determine the structure of crystalline Li(MeNH2)4: we will be preparing the fully deuterated analogue. Our investigations into the magnetic state of this expanded metal using EMU has revealed two magnetic transitions. The use of neutron diffraction will allow us to not only determine the structure of Li(MeNH2)4, which is currently not known, but also whether these magnetic transitions are associated with any structural phase transition. The existence of any reflections arising from magnetic ordering of the lowest phase will also be determined.
