Abstract
Triphenylbismuth bis(3,4-dimethylbenzenesulfonate) Ph3Bi(OSO2C6H3Me2-3,4)2 (I) has been synthesized by the reaction between triphenylbismuth and 3,4-dimethylbenzenesulfonic acid in the presence of tert-butylhydroperoxide (1: 2: 1 mol) in ether. The bismuth atom in complex I has a trigonal bipyramidal coordination to arenesulfonates substituents in axial positions (axial OBiO angle, 173.99(8)°; equatorial CBiC angles, 106.94(11)°, 112.24(11)°, 140.77(11)°). The Bi‒C distances are 2.189(3), 2.192(3), and 2.197(3) A; the Bi‒O distances are 2.284(2) and 2.301(2) A. Some intramolecular contacts are observed between the central atom and the oxygen atoms of sulfonate groups at the maximum equatorial angle (Bi···O 3.122(3), 3.189(4) A).
