C3S4
C3S4 is a semiconducting carbon-sulfur compound that exhibits structural complexity and thermodynamic instability.
About C3S4
C3S4 is a complex binary compound composed of carbon and sulfur. As a semiconducting material, it represents a unique intersection of organic-like bonding and inorganic structural motifs, drawing significant interest for its diverse potential configurations.
Despite its structural variety, the compound is characterized as being above the hull, suggesting it is thermodynamically unstable under standard conditions. Its existence across multiple reported structures highlights the intricate energy landscape inherent to carbon-sulfur systems.
Key Properties
Cross-validated computational properties for C3S4, aggregated across 3 databases.
