About C3Cl2O
C3Cl2O is a complex carbon-based compound containing chlorine and oxygen. As a semiconducting material, it represents a unique arrangement of these elements that has been identified in multiple structural configurations within materials databases.
Due to its position relative to the thermodynamic stability hull, this compound is considered metastable or unstable under standard conditions. Its electronic properties make it a subject of interest for researchers studying the intersection of organic and inorganic chemistry in synthetic material design.
Key Properties
Cross-validated computational properties for C3Cl2O, 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.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of C3Cl2O. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
