The synthesis, spectroscopic investigation, crystal and molecular structure of the [ReBrCl2(SbPh3)3] complex

The [ReBrCl2(SbPh3)3] complex has been obtained in the reaction of [But4N]2[ReBr3Cl2(NO)] with an excess of triphenylstibine. The halide ions and stibine molecules of [ReBrCl2(SbPh3)3] are arranged in a meridional fashion. The substitution reactions of the nitrosyl ligand are very rare so the formation of the [ReBrCl2(SbPh3)3] compound in this reaction is particularly interesting.
