C2Cs8O8
C2Cs8O8 is a semiconducting, thermodynamically unstable compound composed of carbon, cesium, and oxygen.
About C2Cs8O8
C2Cs8O8 is a complex carbon-cesium-oxygen compound characterized by its semiconducting electronic nature. Its composition suggests a unique structural arrangement of carbon and oxygen units coordinated by a high density of cesium cations, placing it in a specialized category of inorganic salts.
Due to its position above the thermodynamic hull, this compound is considered inherently unstable under standard conditions. While multiple structural configurations have been identified across materials databases, its tendency to exist in high-energy states makes it a significant subject for theoretical study in solid-state chemistry.
Key Properties
