| dc.description | A new type of hydrated rubidium molybdenum bronze has been synthesized, which was very unstable. It gave a orthorhombic structure with lattice constantsa=3.74(1), b=22.82(7), and c=3.85(1) Ã . Exchange of Na<sup>+</sup> ion with Rb<sup>+</sup> ion took place within 30 s. The exchange reaction, [Na<sup>+</sup>(H2O)n]x[MoO3 <sup> xâ </sup>]+Rb<sup>+</sup> â [Rb<sup>+</sup>(H2O)n]x[MoO3 <sup> xâ </sup>]+Na<sup>+</sup> , took place in both directions by changing the Na<sup>+</sup>/Rb<sup>+</sup> ratio in the mixed solution. A concentration of about 0.05 mol Na in the sample was the minimum value necessary to retain the structure of hydrated sodium molybdenum bronze. We obtained the blue rubidium bronze, Rb0.30MoO3 , by heating hydrated rubidium bronze in nitrogen. This is a new route to producing the metal bronze at low temperature. We also obtained rubidium decamolybdate by heating it in air. This is also a new method for producing rubidium decamolybdate by solid-state reaction. |
