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 octahedrally surrounded by O atoms. The framework is two-dimensional and is built up from edge-sharing (V,Mo)O6 octahedra forming (VMoO6)∞ layers that run parallel to the (001) plane. Li+ ions are situated in position with symmetry 2/m in the interlayer 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 interesting conduction properties. This simulation proposes a model of the lithium conduction pathways. © 2013 Ezzine Yahmed et al.
