NaCl7
NaCl7 is an unstable, semiconducting compound of sodium and chlorine that exists primarily in theoretical or extreme-pressure research contexts.
About NaCl7
NaCl7 is a unique inorganic compound composed of sodium and chlorine. Unlike common table salt, this stoichiometry represents a highly unusual arrangement of elements that challenges standard chemical bonding expectations. Its electronic character is defined as semiconducting, marking it as a subject of interest for fundamental solid-state physics research.
Due to its position above the thermodynamic hull, this compound is considered inherently unstable under ambient conditions. Its existence is primarily documented through computational modeling and high-pressure synthesis studies, where it serves as a fascinating example of how extreme environments can force elements into unconventional structural configurations.
Key Properties
Cross-validated computational properties for NaCl7, 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.
