Synthesis and structure of tri(meta-tolyl)bismuth bis(2,5-dichlorobenzenesulfonate) and tri(para-tolyl)bismuth bis(1-naphthalenesulfonate)

The interaction of tri( meta -tolyl)bismuth with 2,5-dichlorobenzenesulfonic acid in the presence of tert -butyl hydroperoxide in ether has led to tri( meta -tolyl)bismuth bis (2,5-dichlorobenzenesulfonate) (1) yielding 83%. Similarly, tri( para -tolyl)bismuth bis (1-naphthalenesulfonate) (2) has been obtained yielding 78%. Compounds 1 and 2 have also been synthesized by the reaction of triarylbismuth with arenesulfonic acid in the presence of air oxygen yielding up to 20%. The X-ray structural analysis has been carried out on an automatic four-circle D8 Quest Bruker diffractometer (CCD detector, Мо Kα -radiation, λ = 0.71073 Å, graphite monochromator) at 293 K.

The bismuth atoms have a distorted trigonal-bipyramidal coordination. The OBiO axial angles are 179.64(9) and 174.4(2) deg.. respectively; the sums of the CBiC angles in the equatorial plane are 360 deg. The Bi-O bond lengths are 2.291(3), 2.297(3) Å, and 2.269(8), 2.272(7) Å; the intervals of variation in the Bi-C equatorial bond lengths are 2.176(4)-2.187(3) Å and 2.159(10)-2.214(8) Å. Structures 1 and 2 contain intramolecular contacts between the bismuth atoms and the oxygen atom of the sulfonate ligands. The Bi···O=С distances equal 3.309(3), 3.518(3) Å, and 3.355(14), 3.458(15), which is less than the sum of the Van der Waals radii of bismuth and oxygen (3.59 Å). Crystals 1 and 2 contain intermolecular contacts H∙∙∙O (2.44-2.72 Å and 2.53-2.65 Å); intermolecular contacts Cl∙∙∙Н (2.81 Å) are present in crystals 1.
