title: Lithium vanado(V)molybdate(VI), Li[VMoO6].
abstract: Brannerite-type Li[VMoO6] has been synthesized by a solid state reaction route. The V and Mo atoms statistically occupy the same site with mirror symmetry and are octa-hedrally surrounded by O atoms. The framework is two-dimensional and is built up from edge-sharing (V,Mo)O6 octa-hedra forming (VMoO6)∞ layers that run parallel to the (001) plane. Li(+) ions are situated in position with symmetry 2/m in the inter-layer space. The bond-valence analysis reveals that the Li(+) ionic conductivity is along the [010] and [110] directions, and shows that this material may have inter-esting conduction properties. This simulation proposes a model of the lithium conduction pathways.
