BeF4
BeF4 is an unstable, semimetallic beryllium fluoride compound characterized by a high degree of structural polymorphism.
About BeF4
BeF4 is a binary compound composed of beryllium and fluorine that exhibits semimetallic electronic characteristics. Its structural configuration is notable for being highly diverse, as evidenced by the numerous reported arrangements found across various materials databases.
Due to its position above the thermodynamic hull, this compound is considered inherently unstable under standard conditions. Despite this, its unique electronic nature makes it a subject of interest for researchers investigating the limits of beryllium-based chemical systems.
Key Properties
Cross-validated computational properties for BeF4, 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.
