A new type of crystal of glycylglycine (GlyGly) hydrate was crystallized from an aqueous solution, and the structure of the crystal has been determined by x-ray diffraction. The crystal is monoclinic, and the space group is C2/c, with the cell constants of a Γ 15.941(2) A Λ, b Γ 4.774(2) A Λ, c Γ 19

β¦ Synopsis
An indirect result of the development of a thin-film battery using a polymer-salt electrolyte is the new possibilities this provides for following, by fast in situ X-ray diffraction techniques, the structural changes associated with solid-state reactions under realistic electrochemical conditions. This will be illustrated for the (Li 1 polymer-salt electrolytelV,O,,) thin-film battery, where the stepwise intercalation of Li+ into V,O,, to produce successively Li,V,O,,, x = 1,4 and 8, during cell discharge., is of special interest. We can show that V,O,, is indeed an intrinsically favourable cathode material in thin-film polymer battery concepts, and that development effort should be focused on battery design features rather than on a search for alternative cathode materials. The wide range of solid-state electrochemical phenomena that this technique can probe is immediately clear.
