Li2VOF5
Li2VOF5 is a stable, wide-gap insulating material composed of lithium, vanadium, oxygen, and fluorine.
About Li2VOF5
Li2VOF5 is an insulating compound composed of lithium, vanadium, oxygen, and fluorine. Its electronic character is defined by a wide band gap, which is characteristic of stable, non-conductive inorganic structures.
Because it resides near the thermodynamic hull, this material is considered a viable candidate for experimental synthesis. Its unique chemical composition allows researchers to investigate the interplay between transition metal centers and halide-oxide environments.
Key Properties
Cross-validated computational properties for Li2VOF5, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
As a relatively unique inorganic compound, Li2VOF5 serves as a distinct example of how complex lithium-based oxyfluorides can maintain structural stability. While it currently lacks direct structural siblings in this specific class, its position near the thermodynamic hull suggests it may share the favorable synthesis potential found in other high-stability lithium-based insulators.
