Na2CN2
sodium cyanamide · disodium cyanamide
Sodium cyanamide is a stable, insulating salt composed of sodium and the cyanamide anion.
About sodium cyanamide
Sodium cyanamide is a stable inorganic compound composed of sodium, carbon, and nitrogen. It is characterized by its wide-gap electronic structure, which classifies it as an insulator under standard conditions.
As a thermodynamically stable material residing on the convex hull, it represents a robust phase in nitrogen-containing chemistry. Its structural integrity and electronic properties make it a subject of interest for researchers investigating stable salt-like frameworks.
Key Properties
Cross-validated computational properties for sodium cyanamide, 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.
