Antimonides (sometimes called stibnides or stibinides) are compounds of antimony with more electropositive elements. The antimonide ion is but the term refers also to any anionic derivative of antimony.
Antimonides are often prepared by heating the elements.[1] ntimony by alkali metals or by other methods leads to alkali metal antimonides of various types.[2] Known antimonides include isolated ions (in and). Other motifs include dumbbells in, discrete antimony chains, for example, in, infinite spirals (in NaSb, RbSb), planar four-membered rings, cages in, and net shaped anions in .
Some antimonides are semiconductors, e.g. those of the boron group such as indium antimonide. Being reducing, many antimonides are decomposed by oxygen.
