Au1P1Sr2
Au1P1Sr2 is a semiconducting ternary phosphide compound composed of gold, phosphorus, and strontium.
About Au1P1Sr2
Au1P1Sr2 is a complex phosphide compound containing gold and strontium. As a semiconducting material, it represents a niche area of inorganic chemistry where transition metals and alkaline earth elements combine to form unique electronic environments. Its structural diversity is highlighted by numerous reported configurations in crystallographic databases. Because it resides above the thermodynamic stability hull, this compound is considered metastable, making it a subject of interest for researchers studying synthesis pathways and phase stabilization. Its existence provides insight into the intricate bonding preferences found in ternary phosphide systems.
Key Properties
Cross-validated computational properties for Au1P1Sr2, aggregated across 2 databases.
