About cryolite-type sodium iron fluoride
Na3FeF6 is a thermodynamically stable inorganic compound that exists as a wide-gap insulator. Its structural integrity on the convex hull makes it a significant subject for researchers investigating fluoride-based materials and their fundamental electronic properties. The compound has been characterized across multiple structural databases, reflecting its well-defined nature in solid-state chemistry. It serves as a model system for understanding the coordination environments of iron within complex fluoride lattices, which is essential for predicting the behavior of similar ionic materials under varying conditions. Its insulating character and stability suggest potential utility in specialized electrochemical or optical applications where stable, non-conductive fluoride frameworks are required.
Key Properties
Cross-validated computational properties for cryolite-type sodium iron fluoride, 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.
