B2F3
B2F3 is an unstable, semiconducting binary compound of boron and fluorine characterized by a variety of known structural arrangements.

About B2F3
B2F3 is a binary compound composed of boron and fluorine that exhibits semiconducting electronic properties. Its existence is marked by a diverse range of reported structural configurations, reflecting the complex bonding landscape inherent to boron-fluorine systems.
Due to its position above the thermodynamic hull, B2F3 is considered a metastable or unstable phase under standard conditions. This characteristic makes it a subject of interest for researchers investigating high-energy chemical environments and the fundamental limits of boron-based material stability.
Key Properties
Cross-validated computational properties for B2F3, aggregated across 2 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.
