stannides
Stannides are a broad class of tin-containing compounds in which tin carries a negative formal oxidation state. They arise in inorganic chemistry as intermetallic salts and clusters formed by reducing tin with highly electropositive metals, as well as in organometallic chemistry where tin bears a negative charge in organostannide species. The term covers both tin-centered anions in Zintl-type materials and organostannide reagents used in synthesis.
Inorganic stannides often occur as solid-state salts or polystannide networks balanced by alkali or alkaline-earth cations.
Organostannide chemistry refers to tin-centered anions in which tin bears a negative charge bonded to carbon
Preparation of stannides generally involves reduction of tin-rich precursors, such as tin halides or tin-containing alloys,
Stannides have academic importance for understanding bonding in tin-rich materials and potential applications in materials science,
