H3Pt
H3Pt is a metallic platinum-hydrogen compound that exhibits significant structural complexity and is generally considered thermodynamically unstable.

About H3Pt
H3Pt is a metallic platinum-hydrogen compound characterized by a complex structural landscape. Despite its metallic electronic signature, it remains a challenging material to synthesize due to its position above the thermodynamic hull, suggesting significant instability under ambient conditions.
Its existence is primarily documented through extensive structural studies, reflecting a high level of interest in platinum-based hydrides. These materials are investigated for their potential roles in advanced hydrogen storage and high-pressure physics applications.
Key Properties
Cross-validated computational properties for H3Pt, 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.
