ZrCl3
ZrCl3 is a thermodynamically stable semiconducting binary halide compound of zirconium and chlorine.
About ZrCl3
ZrCl3 is a stable binary halide compound composed of zirconium and chlorine. As a semiconducting material, it represents a significant point of study within the broader landscape of transition metal halides, characterized by its presence on the convex hull of stability. Its structural chemistry is well-documented, reflecting a robust arrangement that is highly favored in solid-state synthesis.
The compound is primarily utilized in fundamental materials science research to probe the electronic behavior of low-dimensional halides. Because it is thermodynamically stable, it serves as a reliable reference point for experimentalists investigating the coordination chemistry of zirconium and the potential for electronic tuning in metal-halide systems.
Key Properties
Cross-validated computational properties for ZrCl3, 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.
