Abstract

Dilute aqueous solutions of Rhodium(III) at the Cl−/Rh(III) ratios 4.86 and 10.7 have been X-ray examined. Octahedral [FORMULA OMITTED] and Rh(H2O)3Cl3 complexes are the species which are consistent with the correlation functions and the structure functions. The average number of bonded chloride ions per Rhodium atom has been determined and the reliability of the structural information is critically examined. The influence of the temperature on the substitution of water molecules by chloride ions is confirmed by using Raman spectroscopy
