Abstract:
The forms of Rh(III) in nitric acid solutions are studied by 14N, 15N, 17O, and 103Rh NMR and electronic absorption spectra. At HNO3 concentrations below 5 mol/l, rhodium mainly exists as low-nuclear oligomers with a bridging fragment Rh(μ-OH)(μ-ONO2)Rh; terminal positions of the central atoms are occupied by water molecules. It was found that the isotopic equilibrium 14NO– 3/15NO– 3of the bridging ligand sets in at an abnormally high rate, at which the isotopic exchange H2 17O/H2 16O of the terminal ligands also occurs in the dimers and trimers. The formation of low-nuclear oligomers is a common feature of Rh(III) complexes in aqueous solutions with ligand deficiency in the system. The possibility of isolating rhodium from nitric acid solutions using different methods is predicted.
