It is shown that lithium can be oxidatively extracted from Li/sub 2/MoO/sub 3/ at room temperature using Br/sub 2/ in CHCl/sub 3/. The delithiated oxides, Li/sub 2-x/MoO/sub 3/ (O < less than or equal to 1.5) retain the parent ordered rocksalt structure. Complete removal of lithium from Li/sub 2/MiO/sub 3/ using Br/sub 2/ in CH/sub 3/CN results in a poorly crystalline MoO/sub 3/ that transforms to the stable structure at 280/sup 0/C. Li/sub 2/MiO/sub 3/ undergoes topotactic ion-exchange in aqueous H/sub 2/SO/sub 4/ to yield a new protonated oxide, H/sub 2/MoO/sub 3/.
