Carbon monosulfide is a highly reactive and unstable diatomic molecule composed of carbon and sulfur.
About Carbon monosulfide
Carbon monosulfide is a diatomic molecule consisting of carbon and sulfur. It is characterized by a metallic electronic structure and is known to be thermodynamically unstable, typically existing as a highly reactive intermediate rather than a bulk solid material.
Due to its instability, this compound is primarily of interest in astrophysical studies and specialized chemical synthesis. Its transient nature makes it a challenging subject for experimental observation, though it has been extensively documented across numerous structural databases.
Key Properties
Cross-validated computational properties for Carbon monosulfide, aggregated across 4 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.
