Na3SbF6
Na3SbF6 is a wide-band-gap insulating compound containing sodium, antimony, and fluorine that exhibits multiple structural variations.
About Na3SbF6
Na3SbF6 is a complex fluoride compound composed of sodium, antimony, and fluorine. As a wide-band-gap insulator, it exhibits distinct electronic properties characteristic of highly ionic fluoride frameworks.
While it has been documented across multiple structural databases, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized and studied in various structural forms, it may require specific conditions to maintain stability compared to more robust phases.
Key Properties
Cross-validated computational properties for Na3SbF6, 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.
