Abstract
Rhodium–tin complexes, formed in aqueous hydrochloric acid solutions of RhCl3 and SnCl2, have been investigated by 119Sn Fourier-transform n.m.r. spectroscopy. Satellite peaks due to the 117Sn isotope revealed fast intramolecular scrambling of the ligands. The redox process between rhodium(III) and tin(II) species to form a rhodium(I) complex with five tin(II) ligands was demonstrated at a molar ratio of [Sn] : [Rh]= 6 : 1. Nuclear magnetic resonance properties of the rhodium(I) complex and of a series of [Rh(SnCl3)nCl6–n]3–(n= 1–5) complexes are determined and discussed.Keywords
