Infobox references

Cesium cyanide (chemical formula: CsCN) is the cesium salt of hydrogen cyanide. It is a white solid, easily soluble in water, with a smell reminiscent of bitter almonds, and with crystals similar in appearance to sugar. Caesium cyanide has chemical properties similar to potassium cyanide and is very toxic.

Production[edit]

Hydrogen cyanide reacts with cesium hydroxide giving cesium cyanide and water:[2]

HCN + CsOH → CsCN + H2O.
