The compounds Ph4Sb[O(O)CC6H3(OH)2-2,5] (1), Ph4Sb[O(O)CC6H3(OH)2-2,6] (2) and [Ph4Sb]+[Ph4Sb(O2C6H3CO2H)]−(3) were obtained through the interaction of pentaphenylantimony with 2,5-; 2,6- and 2,3-dihydroxybenzoic acids in toluene. The structure of synthesized compounds and the coordination type of antimony atoms in 1, 2 and 3 depend on the location of hydroxyl groups in the benzene ring. The antimony atoms in 1 and 2 have distorted trigonal-bipyramidal coordination, through to different degrees. The antimony atom in the anion of compound 3 is hexacoordinated with [C4O2]− surroundings. The compounds 1,2 and 3 have been characterized by elemental analysis, IR- and NMR-spectroscopy, X-ray analysis.
