WCl3
WCl3 is a metastable, semimetallic tungsten chloride compound.
About WCl3
WCl3 is a tungsten-based chloride characterized by its near-zero-gap electronic structure, placing it in the semimetallic regime. As a metastable compound, it represents a complex phase within transition metal halides that requires specific conditions for synthesis and preservation.
Its significance lies in its unique electronic configuration, which distinguishes it from more conventional insulating halides. The material is a subject of interest for researchers investigating the interplay between tungsten d-orbitals and chlorine coordination in low-dimensional or cluster-based architectures.
Key Properties
Cross-validated computational properties for WCl3, 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.
