Tetraarylantimony acylates were obtained from pentaarylantimony and triarylantimony diacylates in 87-98% yields. According to X-ray diffraction data, triphenylantimony dicynnamate Ph3Sb[OC(O)CH= CHPh]2, tetra-p-tolyl monophthalate (p-CH3C6H4)4SbOC(O)C 6H4COOH-o, and tetraphenylantimony salicylate Ph4SbOC(O)C6H4OH-o are trigonal-bipyramidal antimony complexes having axial carboxylic moieties. In the first and third compounds, antimony is coordinated at the esteric carbonyl oxygen, and in the second and third compounds, the carbonyl oxygen enters intramolecular H bonding with the hydrogen atoms of the free carboxy (hydroxy) groups.
