This compound serves as a critical reagent in organic synthesis and industrial catalysis. Its ability to act as a Lewis acid and its unique coordination chemistry make it an essential component in various chemical manufacturing processes.
Key Properties
Cross-validated computational properties for Cuprous chloride, 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.
