Mn3F8
Mn3F8 is a metastable semiconducting compound composed of manganese and fluorine that is primarily studied for its structural complexity.
About Mn3F8
Mn3F8 is a semiconducting manganese fluoride characterized by its metastable nature. As a complex fluoride, it represents a specialized area of study within inorganic chemistry, offering unique structural configurations that distinguish it from more common binary fluoride compounds. Its electronic properties suggest potential utility in niche semiconductor applications where specific manganese-fluorine coordination is required. The material is notable for its structural diversity, with multiple reported phases documented across scientific databases. This complexity makes it a subject of interest for researchers investigating the synthesis and stability of non-equilibrium fluoride systems.
Key Properties
Cross-validated computational properties for Mn3F8, 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.
