Sodium hydrosulfide is a stable, insulating inorganic hydride that functions as a key reagent in chemical manufacturing and sulfur-based synthesis.
About Sodium hydrosulfide
Sodium hydrosulfide is a stable inorganic compound that exists as a wide-band-gap insulator. Its presence on the thermodynamic convex hull highlights its structural robustness, making it a well-documented subject in materials science with numerous reported configurations across structural databases. Beyond its fundamental interest as a hydride, this material serves as a versatile reagent in industrial chemical processes. Its unique chemical identity allows it to participate in various sulfur-transfer reactions, bridging the gap between simple hydrogen storage materials and complex industrial precursors.
Key Properties
Cross-validated computational properties for Sodium hydrosulfide, 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.

How It Compares
Within the hydrogen storage hydrides class.
Unlike the light metal hydrides such as LiH or MgH2, which are primarily investigated for their high gravimetric hydrogen density, NaHS incorporates sulfur into its anionic framework. This structural distinction places it in a unique niche compared to binary hydrides like AlH3 or BH3, as the inclusion of the hydrosulfide group significantly alters its chemical reactivity and thermodynamic profile relative to the simpler alkaline earth hydrides like CaH2.
