Abstract
Triphenylantimony dipropionate Ph3Sb[OC(O)C2H5]2was prepared by reacting triphenylantimony dibromide with sodium salt of propionic acid in toluene at 90°C. The structure of the compound was determined by X-ray diffraction. The coordination of the Sb atom in the compound is a trigonal bipyramid with the carboxylic groups in the axial positions. The Sb(1)–C(Ph)eqdistances vary in the 2.099(7)–2.135(6) Å range; the Sb(1)–O(1,3) distances are 2.113(5) and 2.109(5) Å, respectively. The value of the O(1)Sb(1)O(3) axial angle is 175.0(2)°.
