FeSb

FeSb is a metallic compound categorized within the broader family of skutterudite-related materials. As a metastable phase, it represents a complex structural arrangement of iron and antimony that challenges conventional synthesis pathways, making it a subject of significant interest for researchers studying phase stability and electronic behavior in binary pnictides. Its metallic nature distinguishes it from the semiconducting members often sought for thermoelectric applications, providing a unique baseline for understanding electron transport in this structural class. The compound's existence across numerous reported structures highlights the structural diversity inherent in iron-antimony systems, offering a rich landscape for investigating how atomic coordination influences material properties. While its metastability requires precise control during fabrication, it remains a critical reference point for mapping the electronic landscape of iron-based pnictides.
