Antimonides (sometimes called stibnides or stibinides) are compounds of antimony with more electropositive elements. The antimonide ion is Sb but the term refers also to any anionic derivative of antimony.

Antimonides are often prepared by heating the elements.ntimony by alkali metals or by other methods leads to alkali metal antimonides of various types. Known antimonides include isolated Sb ions (in Li₃Sb and Na₃Sb). Other motifs include dumbbells Sb4−2 in Cs₄Sb₂, discrete antimony chains, for example, Sb8−6 in SrSb₃, infinite spirals (Sb)_n (in NaSb, RbSb), planar four-membered rings Sb2−4, Sb3−7 cages in Li₃Sb₇, and net shaped anions Sb2−3 in BaSb₃.

Some antimonides are semiconductors, e.g. those of the boron group such as indium antimonide. Being reducing, many antimonides are decomposed by oxygen.
