Na3MnF6
Na3MnF6 is a metastable, semimetallic fluoride compound containing sodium and manganese.
About Na3MnF6
Na3MnF6 is a complex fluoride compound composed of sodium, manganese, and fluorine. Its electronic structure exhibits semimetallic behavior, characterized by a near-zero band gap that distinguishes it from typical insulating fluoride salts.
Due to its position above the thermodynamic hull, this compound is considered a metastable phase. While it has been documented across multiple structural databases, its relative instability suggests it may require specific synthetic conditions to be stabilized or observed in practical settings.
Key Properties
Cross-validated computational properties for Na3MnF6, 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.
