dinitrogen trioxide · nitrogen sesquioxide
Dinitrogen trioxide is a reactive and unstable nitrogen oxide that functions primarily as a chemical intermediate.
About dinitrogen trioxide
Dinitrogen trioxide is a binary nitrogen oxide that exists as a semiconducting molecular compound. Its electronic structure and bonding characteristics make it a subject of interest in fundamental chemical studies, particularly regarding the behavior of nitrogen-oxygen species.
Due to its thermodynamic position above the hull, this compound is considered inherently unstable under standard conditions. It typically functions as a transient or reactive intermediate in specialized chemical processes rather than a stable bulk material.
Key Properties
Cross-validated computational properties for dinitrogen trioxide, 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.
