A chemical compound formed when antimony combines with another element, usually a metal, such as zinc antimonide or indium antimonide.
From antimony + -ide (suffix for binary compounds). Stabilized in modern chemistry nomenclature in the 19th century as element chemistry became more systematized. The -ide suffix signals 'compound of' (like oxide, sulfide, chloride).
Antimonides are secretly important in modern electronics—indium antimonide is used in infrared detectors and high-speed semiconductors. A word that sounds medieval-alchemical actually refers to 21st-century nanotechnology.
