C2Cl2F6
1,2-dichloro-1,1,2,2-tetrafluoroethane · CFC-114, Freon 114, R-114
This compound is a chlorofluorocarbon that was historically utilized as a refrigerant and aerosol propellant. Due to its environmental impact on the ozone layer, its production and use have been significantly restricted under international agreements.
Key Properties
Cross-validated computational properties for 1,2-dichloro-1,1,2,2-tetrafluoroethane, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
