About SrN6
SrN6 is a nitrogen-rich inorganic compound that exhibits wide-band-gap insulating behavior. Its structural complexity and electronic properties make it a subject of significant interest in high-pressure materials science, where nitrogen-rich frameworks are often investigated for their unique bonding characteristics.
As a near-hull material, SrN6 is considered a viable target for experimental synthesis. Its stability profile suggests that it may be successfully accessed under specific laboratory conditions, positioning it as a promising candidate for researchers exploring novel energetic materials and nitrogen-based solid-state chemistry.
Key Properties
Cross-validated computational properties for SrN6, 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.
