AuCl2
AuCl2 is a stable, semiconducting inorganic compound composed of gold and chlorine.
About AuCl2
AuCl2 is a gold-based chloride compound that exhibits semiconducting electronic behavior. As a thermodynamically stable phase residing on the convex hull, it represents a well-defined structural arrangement of gold and chlorine atoms that maintains integrity under standard conditions. Its stability and electronic profile make it a subject of interest for fundamental studies in inorganic chemistry and materials synthesis. The compound has been extensively documented, with numerous structural variations reported across major materials databases, reflecting its significance in solid-state research. These structural insights provide a foundation for understanding how gold-halogen interactions influence the electronic properties of the resulting lattice.
Key Properties
Cross-validated computational properties for AuCl2, 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.
