Аннотация: The interaction of rhodium(III) aqua ions with nitrate ions in 3-16 M nitric acid solutions has been studied by Rh-103 and N-15 NMR and Raman spectroscopy. The mononuclear complexes [Rh(H2O)(6-n)(NO3)(n)](3-n) (n = 1-4) were found to be the only form of rhodium(III) existing in the solutions with the metal concentration in the rangПоказать полностьюe 0.2-1.3 M. The dynamics of the H2O -> NO3- substitution process was studied at 80 degrees C. An increase in the average number of nitrate groups bonded to rhodium with increasing concentration of nitric acid was also determined. The fine crystalline salt Rb(4)trans-[Rh(H2O)(2)(NO3)(4)][Rh(NO3)(6)] was obtained by solvothermal concentration of the rhodium nitric acid solution on addition of rubidium nitrate. The structure of the salt was solved by the powder X-ray diffraction method, with monodentate coordination of nitrato ligands found for both the [Rh(NO3)(6)](3-) and trans-[Rh(H2O)(2)(NO3)(4)](-) anions.
