Manganese trifluoride · Manganese(III) fluoride
Manganese trifluoride is a stable, semiconducting inorganic compound widely utilized as a specialized fluorinating agent in various chemical syntheses.
About Manganese trifluoride
Manganese trifluoride is a thermodynamically stable inorganic fluoride that crystallizes in a distinct, well-documented structural arrangement. As a semiconducting material, it serves as a critical chemical reagent in synthetic organic and inorganic chemistry, particularly where controlled fluorination is required.
Its stability on the convex hull underscores its reliability as a chemical precursor. With a vast number of reported structures across major databases, it remains a heavily investigated subject for researchers focused on transition metal fluorides and their electronic behaviors.
Key Properties
Cross-validated computational properties for Manganese trifluoride, 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.
