As3Ir
As3Ir is a thermodynamically stable, semimetallic alloy composed of arsenic and iridium that is primarily studied for its potential in advanced catalytic applications.
About As3Ir
As3Ir is a distinct platinum-group alloy characterized by its semimetallic electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural configuration within the arsenic-iridium binary system. Its electronic properties make it a subject of significant interest for fundamental studies in condensed matter physics and catalysis. The material is noted for its structural diversity, with numerous reported configurations across major materials databases, highlighting its complex coordination environment. This stability and electronic character position it as a valuable candidate for exploring high-performance catalytic mechanisms where surface interaction and electronic density are critical.
Key Properties
Cross-validated computational properties for As3Ir, aggregated across 4 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloys, As3Ir occupies a unique niche compared to siblings like As2Ir and As2Pt. While many members of this class, such as the ruthenium-based P3Ru or the palladium-containing BaPd, exhibit varied stoichiometric ratios and electronic behaviors, As3Ir is distinguished by its specific arsenic-rich composition and its confirmed thermodynamic stability. It serves as a critical reference point for understanding how varying the pnictogen content influences the overall stability and catalytic potential of iridium-based intermetallic compounds.
