Antimony pentafluoride is a powerful, thermodynamically stable Lewis acid widely used as a key component in superacid chemistry.
About Antimony pentafluoride
Antimony pentafluoride is a highly reactive inorganic compound recognized for its exceptional Lewis acidity. As a thermodynamically stable species, it serves as a foundational component in the synthesis of powerful superacid systems, which are essential for facilitating difficult chemical transformations. Its insulating electronic character underscores its role as a specialized reagent rather than a conductive material. Due to its intense reactivity, it is handled with extreme care in industrial and laboratory settings. It remains a subject of significant interest in structural chemistry, with numerous documented configurations reflecting its complex coordination behavior.
Key Properties
Cross-validated computational properties for Antimony pentafluoride, 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.
