NiF4
NiF4 is a semiconducting nickel fluoride compound that is thermodynamically unstable and exists in a variety of structural forms.
About NiF4
NiF4 is a binary nickel fluoride compound characterized by its semiconducting electronic nature. Despite its simple chemical composition, it exhibits significant structural diversity, as evidenced by the numerous distinct configurations identified in materials databases.
Due to its position above the thermodynamic hull, this compound is considered inherently unstable under standard conditions. Its study remains a niche but important area for researchers investigating high-oxidation state transition metal fluorides and the limits of chemical synthesis.
Key Properties
Cross-validated computational properties for NiF4, aggregated across 2 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.
