carbon disulfide · carbon bisulfide
Carbon disulfide is a highly volatile and reactive insulating liquid widely used as a chemical solvent and precursor in industrial manufacturing.
About carbon disulfide
Carbon disulfide is a simple inorganic compound characterized by its insulating electronic nature. Despite its structural simplicity, it exhibits significant polymorphism, with numerous reported arrangements documented across materials databases. Its chemical behavior is marked by high volatility and reactivity, which defines its utility in synthetic chemistry. Because it sits above the thermodynamic hull, it is considered a metastable species that requires careful handling and specific conditions for synthesis and storage. Its role as a solvent and chemical intermediate remains vital in various industrial processes, leveraging its unique ability to dissolve a wide range of organic and inorganic substances.
Key Properties
Cross-validated computational properties for carbon disulfide, 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.
