It is shown that lithium can be oxidatively extracted from Li//2 MoO//3 at room temperature using Br//2 in CHCl//3. The delithiated oxides, Li//2// minus //x MoO//3 (0 less than multiplied by less than equivalent to 1. 5) retain the parent ordered rocksalt structure. Complete removal of lithium from Li//2MoO//3 using Br//2 in CH//3CN results in a poorly crystalline MoO//3 that transforms to the stable structure at 280 degree C. Li//2MoO//3 undergoes topotactic ion-exchange in aqueous H//2SO//4 to yield a new protonated oxide, H//2MoO//3.
