Synthesis and structures of organoantimony and organobismuth derivatives of 4-sulfophenol and 2,4-disulfophenol

Tetraphenylbismuth 4-hydroxybenzenesulfonate (I) and tetraphenylantimony 4-hydroxybenzenesulfonate (II) are synthesized in yields up to 80% by the reaction of pentaphenylbismuth and pentaphenylantimony, respectively, with 4-sulfophenol. Compounds I and II are also prepared by the ligand redistribution reaction from pentaphenyl compounds of bismuth and antimony and triphenylbismuth bis(4-hydroxybenzenesulfonate) and triphenylantimony bis(4-hydroxybenzenesulfonate), respectively, in yields up to 87%. The recrystallization of compounds I and II from water gives crystalline hydrates Ph4BiOSO2C6H4(OH-4) ? H 2O (III) and Ph4SbOSO2C6H 4(OH-4) ? H2O (IV). Pentaphenylbismuth and pentaphenylantimony react with 2,4-disulfophenol in acetone, regardless of the ratio of the starting reactants, to form bis(tetraphenylbismuth) 4-hydroxybenzene-1,3-disulfonate (V) and bis(tetraphenylantimony) 4-hydroxybenzene-1,3-disulfonate (VI) in yields up to 74%. According to X-ray diffraction data, coordination of the bismuth atoms in compound I is trigonal-bipyramidal with the axial oxygen atom of the 4-hydroxybenzenesulfonate group (Bi???O 2.764 A). In compound II, coordination of the Sb atom is tetrahedral (CSbC angles 106.2°-112.3°). In crystal III, the distances between the central atom and the nearest oxygen atoms of the arenesulfonate group and the hydrate water molecule are 3.094 and 3.125 A, respectively. Crystals V and VI consist of doubly charged anions of 2,4-disulfophenol and several distorted tetrahedral cations of tetraphenylbismuthonium (CBi(1)C, CBi(2)C angles and Bi(1)-C, Bi(2)-C bond lengths vary in the intervals 102.1°-122.7°, 105.4°-114.0° and 2.103-2.230, 2.187-2.209 A, respectively) and tetraphenylantimonium (CSb(1)C, CSb(2)C angles and Sb(1)-C, Sb(2)-C bond lengths 106.3°-112. 2°, 101.3°-122.4° and 2.095-2.110, 2.092-2.123 A, respectively). The Bi(1) and Sb(2) atoms are coordinated by one of the oxygen atoms of the 2,4-disulfophenol anions (distances Bi(1)???O(3) 2.803, Sb(2)???O(1), 2.704 A). Nauka/Interperiodica 2007.
