Preparation

It can be prepared by the reaction of

antimony(III) oxide Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves i ...

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 X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles ...

. 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 interaction An intermolecular force (IMF) (or secondary force) is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighbouring particles, e.g. a ...
