Antimony is the chemical element with atomic number 51 and symbol . It is a metalloid. Its common oxidation states include and . Elemental antimony is brittle, while its compounds and alloys have distinct materials applications; potassium antimony tartrate is an example of a coordination compound rather than the free element.[ref]
A pentavalent antimony chloride whose solution behaviour depends strongly on hydrolysis and chloride concentration.
The chloride historically called butter of antimony. Hydrolysis on dilution can produce oxychloride-containing precipitates.
The sulfide with composition ; the mineral stibnite and a freshly precipitated material can differ in appearance and structure.
Potassium antimony tartrate is an antimony-containing salt with potassium counterions and tartrate ligands, historically called tartar emetic. Its composition includes both inorganic metal centres and organic coordinating groups.
The tartrate provides oxygen donor sites that bind antimony. This makes the compound an example of how coordination chemistry joins metal-ion chemistry with the stereochemistry and functional groups of an organic ligand.
Historical pharmaceutical preparation; its composition and clinical use must be identified by edition. [ref]

The +3 oxidation state of antimony. The actual aqueous species can depend on pH, hydrolysis and ligands; a bare ionic formula is an analytical shorthand.

Antimony is a chemical element with the symbol **Sb** (from the Latin "stibium") and atomic number **51**. It is a metalloid, which means it has properties of both metals and non-metals. Antimony is known for its brittle nature and is often found in nature primarily in the form of various sulfide minerals, particularly stibnite (Sb₂S₃).
