Tetraphenylantimony phenoxyacetate (I) was synthesized by reacting pentaphenylantimony with phenoxyacetic acid (at a molar ratio of 1 : 1) in toluene. Tetraphenylantimony ethylmalonate (II) was synthesized from triphenylantimony and malonic ether in the presence of hydrogen peroxide (1 : 1 : 1) in diethyl ether. According to X-ray diffraction data, Sb atoms in compounds I and II have a distorted trigonal bipyramidal coordination to the axial oxygen atoms. The axial OSbCax angles and Sb-Cax distances are, respectively, 176.31(6)° and 2.177(2) Å for I and 179.40(4)° and 2.162(1) Å for II. The Sb-Ceq distances lie in the intervals of 2.108(2)-2.127(2) Å for I and 2.117(1)-2.128(1) Å for II. In compounds I and II, the Sb-O bond lengths are equal to 2.235(1) Å and 2.250(1) Å, respectively, and the intramolecular contacts Sb···О are equal to 3.402(2) Å and 3.282(1) Å, respectively.
