Lithium hydroxide dihydrate: A new type of icy material at elevated pressure [PDF]
, 2011 We show that, in addition to the known monohydrate, LiOH forms a dihydrate at elevated pressure. The dihydrate involves a large number of H-bonds establishing chains along the direction. In addition, the energy surface exhibits a saddle point for proton
