| Summary: | The complexation in the system Rh(III) – H<sub>2</sub>SO<sub>4</sub> – H<sub>2</sub>O at the room temperature in the dilute sulfuric acid has been studied by 103Rh and 17O NMR. The most stable species in solutions are [Rh<sub>2</sub>(μ-SO<sub>4</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>8</sub>] <sup>2+</sup> and [Rh<sub>2</sub>(μ-OH)(μ-SO<sub>4</sub>)(H<sub>2</sub>O)<sub>8</sub>] <sup>3+</sup>; we have established that the solid «rhodium sulfates” are amorphous glassy phases with variable composition |
