K3CrF6
K3CrF6 is a thermodynamically stable, insulating fluoride compound composed of potassium, chromium, and fluorine.
About K3CrF6
K3CrF6 is a complex fluoride compound characterized by its insulating electronic nature and high thermodynamic stability. As a member of the transition metal fluoride family, it maintains a robust structural framework that sits securely on the convex hull, indicating significant chemical resilience under standard conditions.
This material is of interest to researchers studying inorganic fluorides due to its well-defined structural profile and clear electronic character. Its stability makes it a reliable candidate for fundamental studies into the coordination chemistry of chromium within halide-based lattices.
Key Properties
Cross-validated computational properties for K3CrF6, 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.
