Vanadium pentachloride is a stable, semiconducting inorganic compound containing vanadium and chlorine.

About Vanadium pentachloride
Vanadium pentachloride is a binary halide compound composed of vanadium and chlorine. It is recognized as a thermodynamically stable phase that sits on the convex hull, indicating a robust structural configuration under standard conditions.
As a semiconducting material, it serves as a specialized reagent in inorganic chemistry. Its electronic character and stability make it a subject of interest for researchers investigating vanadium-based precursors and reactive chemical environments.
Key Properties
Cross-validated computational properties for Vanadium pentachloride, 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.
