| Popis: | The synthesis of [Bi(C18H14P(O)SO3)2(DMSO)3](NO3)∙DMSO∙2H2O starting from [Bi6O4(OH)4](NO3)6∙H2O and 2-(diphenylphosphino)benzenesulfonic acid is presented. 31P{1H}-NMR experiments confirm the in situ oxidation of 2-(diphenylphosphino)benzenesulfonic acid to give 2-(diphenylphosphine oxide)benzenesulfonic acid by heating in dimethyl sulfoxide (DMSO). In the presence of [Bi6O4(OH)4](NO3)6∙H2O, subsequent formation of single crystals of the title compound is observed. The crystal structure determination reveals that the bismuth atom shows a [5+4] coordination with short Bi–O distances in the range of 2.278(11) to 2.398(11) Å to the oxygen atoms of DMSO and phosphine oxide groups and with longer Bi–O bonds of 2.74(2) and 2.88(2) Å to the chelating sulfonate groups. |
