La6O6Sb2

La6O6Sb2 is a complex ternary oxoantimonide characterized by its semiconducting electronic structure. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration of lanthanum, oxygen, and antimony atoms that maintains structural integrity under standard conditions. Its existence across multiple reported structures highlights its significance in the systematic exploration of rare-earth pnictide-oxide systems. This compound serves as a valuable subject for investigating the interplay between heavy lanthanide cations and pnictogen-oxygen frameworks, which are often explored for their unique electronic and optical properties. By bridging the gap between simple oxides and complex intermetallics, La6O6Sb2 contributes to the fundamental understanding of chemical bonding in multi-anionic materials.
