✦ Synopsis
The cesium-sodium ion exchange on the hydrated molybdenum bronze was investigated, and the proton in the intralayer site was found to prevent the complete ion-exchange of Cs /Na. The hydrated bronze of Cs with a larger ionic radius showed hydration behavior different than the bronzes of other alkali metals. Furthermore, the low-temperature synthesis route from hydrated molybdenum bronzes to alkali-metal molybdenum bronzes was investigated, and it was found that the route led to the formation of a new Cs molybdenum bronze, which was related to the family of blue alkali-metal molybdenum bronze A 0.3 MoO 3 . The lattice constants of the bronze were a ؍ 19.362(8), b ؍ 7.567(2), and c ؍ 10.506(4) A s , and (°)3(70.121؍ monoclinic system).
