Antimonite
In chemistry an antimonite refers to salts of antimony(III), such as NaSb(OH)4 and NaSbO2 (metaantimonite) which can be prepared by reacting alkali with antimony(III) oxide, Sb2O3.[1] These are formally salts of antimonous acid (antimonious acid[2] ) , "Sb(OH)3" whose existence in solution is dubious, and attempts to isolate it generally form Sb2O3.xH2O, antimony(III) oxide hydrate, which slowly transforms into Sb2O3.[1]
In geology the mineral stibnite, Sb2S3, is sometimes called antimonite.
They can be compared to antimonates, which contain antimony in the +5 oxidation state.
