As a transition metal halide, this compound serves as a critical precursor in organometallic chemistry and the synthesis of tungsten-based materials. Its electronic character and stability profile allow it to function as a reliable building block in specialized chemical processes.
Key Properties
Cross-validated computational properties for WCl4, aggregated across 2 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.
