Solid-state rhodium(III) sulfates and their aqueous solutions were examined by IR and electronic
absorption spectroscopy, thermogravimetry, X-ray powder diffraction analysis, and 103Rh and 17O NMR spectroscopy.
A study of the spontaneous aquation of freshly prepared solutions showed that this process results in
an equilibrium between the subsystems of monomeric and oligomeric complexes. It was found that solid-state
rhodium(III) sulfates vary in phase composition, basically consisting of dimeric and trimeric complexes.
