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
Hydrogen cyanide reacts with cesium hydroxide giving cesium cyanide and water:[2]
- HCN + CsOH → CsCN + H2O.
