LiRh2W
LiRh2W is a semiconducting ternary lithium-rhodium-tungsten alloy that exists in a metastable state.
About LiRh2W
LiRh2W is a complex ternary alloy categorized within the platinum-group metal systems. As a semiconducting material, it represents a unique electronic configuration distinct from the typical metallic behavior associated with its constituent heavy transition metals. Its structural diversity is evidenced by multiple reported configurations across major materials databases. Despite its interesting composition, the compound is characterized as being thermodynamically situated above the hull, suggesting it is likely unstable under standard conditions. This metastable nature makes it a subject of significant interest for researchers investigating the limits of phase stability in lithium-containing transition metal alloys.
Key Properties
Cross-validated computational properties for LiRh2W, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the class of platinum-group alloy catalysts, LiRh2W stands out as a rare lithium-bearing ternary phase compared to more conventional binary systems like LaRh or As2Pt. While many of its siblings in this group exhibit stable, metallic characteristics, LiRh2W is defined by its semiconducting nature and its tendency toward metastability, setting it apart from the more robust, highly symmetric structures often found in the broader catalog of platinum-group catalysts.
