Cesium ozonide is a chemical compound of cesium and is one of the ozonides . It is a red, easily decomposable solid.

Extraction and presentation

Cesium ozonide can be obtained by reacting cesium hyperoxide with ozone and then extracting it with liquid ammonia .

properties

Cesium ozonide is a red solid that crystallizes in two different modifications . The monoclinic structure, which corresponds to that of rubidium ozonide , is stable below 8 ° C. This has the space group P 2 1 / c (space group no. 14) and the lattice constants a = 675.1 pm, b = 626.7 pm, c = 901.5 pm and β = 120.74 °, as well as four formula units per unit cell . At higher temperatures the structure corresponds to the cubic cesium chloride structure with the lattice parameter a = 436.06 pm. The ozonide ion is disordered . Template: room group / 14

Above 53 ° C, cesium ozonide decomposes, releasing oxygen and forming hyperoxide .

If cesium ozonide is dissolved in water, it reacts to form cesium hydroxide and oxygen .
