Diphenylbismuth arenesulfonates Ph2BiOSO2R

Abstract

The corresponding diphenylbismuth arenesulfonates have been synthesized by the interaction of equimolar amounts of triphenylbismuth with mesitylenesulfonic, naphthalene-1-sulfonic, (1S)-(+)-camphor-10-sulfonic and 2,5-dichlorobenzenesulfonic acids (1:1 molar) in ether and the structural characteristics have been found for diphenylbismuth mesitylenesulfonate (1), diphenylbismuth naphthalene-1-sulfonate (2); they are coordination polymers in which the bismuth atoms have a distorted trigonal-bipyramidal coordination with the oxygen atoms of the sulfonate groups in the axial positions (the Bi–O distances are 2.404(4), 2.500(4) Å for 1 and 2.398(14)2.435(13) Å for 2) and the carbon atoms of phenyl substituents in the equatorial positions (the Bi–C distances are 2.221(18)2.250(18) Å). The third position in the equatorial plane is occupied by an unshared electron pair.
