PPt3
PPt3 is a metallic platinum-phosphide alloy that demonstrates significant structural complexity despite its status as a metastable phase.
About PPt3
PPt3 is a metallic compound within the platinum-group alloy catalyst family. Characterized by its lack of a band gap, this material exhibits typical metallic electronic behavior, making it a subject of interest for fundamental studies in transition metal phosphide systems.
Despite its thermodynamic position above the hull, which suggests potential instability, the compound remains a point of significant focus due to its structural diversity. With dozens of reported structures across major databases, it serves as a complex case study for researchers investigating the phase stability of platinum-based alloys.
Key Properties
Cross-validated computational properties for PPt3, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the class of platinum-group alloys, PPt3 stands out for its high degree of structural polymorphism compared to more stable, simple binary phases like As2Pt or IrSe2. While many members of this group exhibit well-defined, stable crystalline lattices, PPt3 represents a more elusive phase that challenges standard synthesis and characterization techniques.
