About H7BrO3
H7BrO3 is a unique inorganic compound characterized by its insulating electronic nature. As a thermodynamically stable material situated on the convex hull, it represents a robust configuration of hydrogen, bromine, and oxygen atoms.
Its structural complexity is evidenced by the multiple reported configurations documented across various databases. This material serves as a significant subject for researchers investigating the fundamental behavior of hydrogen-rich systems in solid-state chemistry.
Key Properties
Cross-validated computational properties for H7BrO3, 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.
