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, id moderately water soluble, and is used as a catalyst in the production of synthetic fibers.

Preparation

It can be prepared by the reaction of antimony(III) oxide with acetic acid:

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

Crystal Structre

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.[1]
