H3N is a stable, insulating hydride of nitrogen and hydrogen that serves as a vital industrial chemical and a potential medium for hydrogen storage.
About Ammonia
H3N, commonly known as ammonia, is a fundamental hydrogen storage hydride characterized by its wide-gap insulating electronic structure. As a thermodynamically stable compound residing on the convex hull, it serves as a robust chemical platform for energy storage and synthesis.
Its significance extends beyond simple storage, as it acts as a primary precursor in the production of nitrogen-based fertilizers and various industrial chemicals. The compound's stability and high hydrogen density make it a subject of extensive structural research across multiple databases.
Key Properties
Cross-validated computational properties for Ammonia, 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.

How It Compares
Within the hydrogen storage hydrides class.
Within the class of hydrogen storage hydrides, H3N stands out as a molecular species compared to the more traditional ionic or metallic hydrides like MgH2, CaH2, or LiH. While those solid-state hydrides are often utilized for their reversible hydrogen desorption properties in structural alloys, H3N functions primarily as a high-density liquid or gaseous carrier, offering a distinct chemical pathway for hydrogen delivery and nitrogen-based fuel cycles.
