Antimony(III) acetate is the compound of antimony with the chemical formula of Sb(CH3CO2)3. It is a white powder, is moderately water-soluble, and is used as a catalyst in the production of polyesters.

Preparation

[edit]

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

Sb2O3 + 3 C4H6O3 → 2 Sb(CH3CO2)3

Structure

[edit]

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.[2]
