Reactions of pentaphenylantimony with triphenylbismuth diacylates yield the corresponding tetraphenylantimony acylates. Triphenylbismuth bis(trichloroacetate) was prepared by oxidation of triphenylbismuth with hydrogen peroxide in the presence of trichloroacetic acid. The structure of triphenylbismuth dibenzoate was determined by single crystal X-ray diffraction. The coordination polyhedron of the central atom is intermediate between trigonal bipyramid and pentagonal bipyramid; the benzoate groups occupy the equatorial position.

Acyloxy derivatives of tetraphenylantimony of the general formula Ph4SbOC(O)R (R = Alk or Ar) have been synthesized by the reaction of pentaphenylantimony with carboxylic acids. Thermolysis of the compounds obtained affords phenyl carboxylates and triphenylstibine in quantitative yields. One of these compounds (R = CH=CHPh) has been studied by X-ray structural analysis. In this compound, the Sb atom has a trigonal-bipyramidal coordination. The Sb-O(Ph)eq distances are in the range 2.103(4)-2.140(5) A; the Sb-C(Ph)ax bond length is 2.167(5) A. The fragment of the residue of cinnamic acid has a delocalized double bond in the carboxylate group.
