Antimony(III) acetate is the antimony salt of acetic acid with the chemical formula of Sb(CH₃COO)₃. It has the appearance of a white powder and is used as a catalyst in the production of synthetic fibers. It can be prepared by the reaction of antimony(III) oxide with acetic acid:

Sb₂O₃ + 6 HC₂H₃O₂ → 2 Sb(C₂H₃O₂)₃ + 3H₂O

The crystal structure of antimony(III) acetate has been determined by X-ray crystallography. It consists of discrete Sb(OAc)₃ monomers with monodentate acetate ligands. The monomers are linked together into chains by weaker C=O···Sb intermolecular interactions.
