About Li5Sn2
Li5Sn2 is a metallic intermetallic compound composed of lithium and tin. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration within the binary lithium-tin system.
This material is characterized by its metallic electronic nature, which distinguishes it from insulating or semiconducting binary compounds. With numerous reported structures across multiple databases, it is a well-documented subject of interest for researchers studying lithium-rich alloy systems.
Key Properties
Cross-validated computational properties for Li5Sn2, aggregated across 5 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.
