N3Cl
N3Cl is a metastable, semiconducting compound composed of nitrogen and chlorine that is of interest for its diverse structural possibilities.

About N3Cl
N3Cl is a nitrogen-rich compound that exhibits semiconducting electronic behavior. Due to its position above the thermodynamic hull, it is considered a metastable material, which presents unique challenges and opportunities for synthesis and structural characterization.
Despite its instability, the compound has attracted significant research interest, evidenced by a wide variety of reported structures across multiple databases. Understanding its bonding environment is essential for researchers investigating high-energy density materials and nitrogen-rich chemistry.
Key Properties
Cross-validated computational properties for N3Cl, 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.
