CaSnF4
CaSnF4 is a metastable, insulating fluoride compound composed of calcium, tin, and fluorine.
About CaSnF4
CaSnF4 is a complex fluoride compound characterized by its insulating electronic nature and wide band gap. As a metastable material, it represents a unique structural arrangement of calcium, tin, and fluorine atoms that requires specific conditions for synthesis and stabilization.
This compound is primarily of interest in fundamental materials science, where its structural diversity—evidenced by multiple reported configurations—makes it a subject of study for understanding fluoride-based lattice dynamics. Its role is largely defined by its potential as a specialized inorganic solid.
Key Properties
Cross-validated computational properties for CaSnF4, 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.
