Antimony(III) acetate explained

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

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

Sb₂O₃ + 3 C₄H₆O₃ → 2 Sb(CH₃CO₂)₃

Structure

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]
