Article abstract of DOI:10.1016/s0020-1693(97)05908-2

The rhodium (III) distibine complexes trans-[Rh(L-L)₂X₂]Y (L-L=Ph₂Sb(CH₂) ₃SbPh₂ or o-C₆H₄(SbMe₂)₂; X=Cl, Br or I; Y=X or BF₄) have been prepared and studied by UV-Vis, ¹H and ¹⁰³Rh NMR spectroscopies and electrospray mass spectrometry. The ¹⁰³Rh NMR spectroscopic data are reported and compared with data on related phosphine and arsine complexes. The single crystal X-ray structure of trans-[Rh{Ph₂Sb(CH₂)₃SbPh₂} ₂Cl₂] [ClO₄] is reported (Rh-Sb=2.594(2), 2.611(2); Rh-Cl=2.369(7) ?).
